1.1.2.4 Post-Update Stability Patch

[h2]Gameplay:[/h2]
  • Dedicated servers now support joining by using IPv6 address.
  • Improved –ip arguments description on dedicated servers.
  • For clarity, changed GameID to Steam GameID when server provides the connection info to player to emphasize that it can only be used by Steam client to join.
  • Join-game menu’s Game ID field now allows the use of 0 in GameIDs
  • Ra-Akar's homing projectiles now despawn when the boss is defeated.

[h2]Graphics:[/h2]
  • Flower Vessel destructibles in Azeos’ Wilderness now correctly leave flower debris on the ground when destroyed.

[h2]Modding[/h2]
  • ModIO mod-collection menu now displays mod size in localized “megabytes/kilobytes/bytes” text whenever unsubscribing from a mod.
  • Mods that are automatically installed because they are dependencies of other mods are now marked as dependencies in the mod menus. They also can no longer be uninstalled manually unless you first uninstall all mods that require them as dependencies.

[h2]Miscellaneous[/h2]
  • Gravestone markers now visually appear over Waypoints and Portals on the map. 
  • Added an “-activateallcontent” argument for dedicated server to automatically activate all available content bundles. If you include this argument in your startup script, you do not have to activate new content bundles individually when the game receives an update. See ARGUMENTS.txt for more information. 
  • Reworded the Crossplay option in the gameplay settings to clarify that this only affects playing with PC players who bought the game on a different storefront. The game currently does not support crossplay between PC and consoles.

[h2]Performance[/h2]
  • Fixed lag spikes that would sometimes happen when bosses temporarily went off-screen. 
  • Improved how menus are initialized to reduce the game’s load time. 
  • Fixed an issue that would cause a lag spike every time a new dungeon started generating. This issue was especially noticeable when starting a new world on a device with few cores. 
  • Fixed a lag spike when connecting to a world using a new character. 
  • Improved how the game finds converters, reducing the game’s load time. 
  • Clients now receive and process animation triggers from the server in a worker thread job instead of on the main thread.

[h2]Bug fixes:[/h2]
  • Fixed issue that caused connections not work if player cancels the join process immediately after starting. 
  • Fixed memory leak when using Thai language. 
  • Fixed discord causing crash at the start of the game. 
  • Fixed dedicated server printing GameID twice to GameID.txt file. 
  • Fixed dedicated server creating some files (GameID.txt, GameInfo.txt, CoreKeeperServerLog.txt) into the folder the game was launched from rather than the folder game exists in. Now the files should always be created to the game folder. 
  • The map is no longer initially blank when opened at high zoom levels using a gamepad. 
  • Poison Berry Walls' explosions should now correctly apply the poison effect. 
  • Fixed a bug where recipe slots would not highlight at the correct times during the in-game tutorial. 
  • Gravestone markers can no longer prevent you from teleporting to a Waypoint or Portal. 
  • Newly hatched pets that have been dropped on the ground are no longer deleted when the world is reloaded. 
  • Fixed a bug where some Abiotic Factor loot was not dropping. 
  • Closing the map using the “back” button on a gamepad no longer triggers offhand item effects. 
  • Caveling Gardeners now pursue targets at a range that allows them to use their melee attack effectively. 
  • Fishing in normal water in the Shimmering Frontier or Passage biomes no longer causes the player to get stuck when trying to pull up their catch. 
  • Fixed a bug where the "caught fish" chat message did not appear if you immediately threw the hook back into the water while having a bait equipped. 
  • Fixed a bug that sometimes prevented the Starlight Nautilus achievement from triggering. 
  • Projectiles should no longer deal damage for extended periods after they've collided with environment. 
  • Minions should now be correctly slowed by mold ground. 
  • Moving during the Core Commander's death animation no longer causes some particle effects to appear in the wrong location. 
  • The skill tree selection SFX no longer has significantly lower volume than other UI sounds. 
  • Getting disconnected from a server while a popup dialog is displayed no longer results in menus still being open in the background when returning to the main menu. 
  • The minimap no longer stays visible in the main menu after getting disconnected from a server. 
  • Pressing Cancel on the Join-Game screen immediately after starting to join no longer causes future join attempts to timeout. 

Notes From the Underground #006

Adventuring in the underground is a lot of fun, but it pays to be prepared...and it looks like our wayward Explorer has been neglecting chores back at their base! Thankfully, they seem to have a knack for problem solving, and they've come up with all sorts of ideas to make things like farming, fishing, and collecting resources much easier!

A transcript of this journal entry has been provided below the image.



[h2]Notes From the Underground #6 - Chore Day [/h2]

I have been on some incredible adventures lately, but boy am I ready to spend some time relaxing at my base! There are just a few chores to tend to before I can really unwind, though. Crops to tend to, fish to catch, and so on. Hmm, if only there were tools or machinery that could reduce the workload a little? I think it’s time to hunker down with a Cave Coffee and come up with some ideas!

How to Harvest?
I’ve so many delicious crops growing, but they tend to sit unharvested while I’m out adventuring, and that’s precious time that could be spent growing more food! Perhaps there is some way I can augment the design of my patented Robot Arm to assist with gardening?

More Efficient Fishing
Is there anything more relaxing than fishing? I’d spend all day fishing if I had the time! I suppose I wouldn’t be making anywhere near as many discoveries if I did that, though. There’s no way I’d ever fully retire my beloved fishing rod, but it’d be nice to come home to a net full of tasty fish after a hard day’s work. Something to think about...

My Aching Back!
I’ve been making good use of the Laboratory Table lately, and the explosives I’ve been crafting have been a real boon when it comes to exploration and gathering resources. An unintended side effect, however, is the pain I’m feeling in my back every time I bend down to pick up the loot I’ve been uncovering. I thought I might train my Subterrier to fetch me items, but he thinks it's a game and won’t bring them back. Maybe this is a task better suited to a machine…

More Ways to Play With Friends Using Dedicated Servers!

Hey there Explorers, we’ve just launched a patch for Core Keeper that includes a cool new update for dedicated servers!

Traversing the underground is always fun with friends, but up until now, Explorers playing on dedicated servers all had to be using the same client to run the game. Well, we’re pleased to report that PC gamers can now play Core Keeper together on the same dedicated servers, whether they’re running the game on Steam, Epic Games, GoG, or the Microsoft Store!

If you want to run a dedicated server that supports players running the game via a different client than the host, you’ll find instructions on how to do this in the README.txt file located in the folders associated with your dedicated server. This is typically found at the following file path when running a server via Steam: "SteamLibrary\steamapps\common\Core Keeper Dedicated Server\README.txt". You can also follow these instructions to open up an existing dedicated server to players running the game via other clients too.

You might be wondering how this update impacts the way mods work on dedicated servers. We’re delighted to report that your mods should still function as intended when playing with folks running the game via different clients so long as all players have the same mods installed.

We hope this will bring even more Explorers together for adventures, base building, boss battles, and camaraderie (or competition, for those who prefer to play PvP!). If you’re looking for folks to play with, make sure you join our Core Keeper community Discord and visit the #🔍-lfg-matchmaking channel to meet your fellow Explorers.

1.1.2.3 Patch Notes

  • Dedicated servers using direct connections can now be joined using the servers IP, Port and Password

  • Dedicated servers now notifies player during start-up if any issues were encountered

Community Update - July 2025

Hi there Explorers! Gosh, it's been a hot minute since we've had a community update. We were doing these weekly at one point, but we think a monthly cadence will be a little more enjoyable for those of you who wish to keep up with all the lovely things going on across our community spaces without these updates dominating your Steam news feeds!

As many of you know by now, the development team takes a little time off during the summer to rest and recuperate. That doesn't mean that there's not plenty of Core Keeper activity going on across our Discord, X, Instagram and BlueSky accounts, though! The community team is still hard at it, bringing you the Core Keeper content you know and love. So, let's take a look at what we've been sharing and what the community has been up to!

[h2]5-Set Fishing Bonus[/h2]
Here's a top tip for all you fishing enthusiasts! Equip the Diving Helm, Kelp Mantle, Scuba Fins, Neptune Necklace, and Goldfish Ring to take your fishing sessions to the next level. Not only will this armour set increase your max health and armour, it'll also offer a bonus to fishing, improve your chance of hooking a fish, increase the odds of a rare fish bite, add 24% of your fishing skill as range damage, AND improve the odds of bait not being consumed when catching a fish. Phew, that's a lot of fishing fun!



[h2]Abiotic Office[/h2]
Have you stumbled upon any scenes from our Abiotic Factor crossover yet? We'll give you a hint! These spawn in the Forgotten Ruins. Perhaps there's some temporal weakness here that allows dimensions to crossover more easily? We can only speculate...
