- fix: Deathmason crashing the game after resurrecting him
- fix: Issue with Deathmason's red portals
- fix: prevent loading corrupted savefile
- fix: enter portal crash loop
- fix: Only living units can acquire pickups
- fix: Skipping a level when an NPC ally finishes a level while you're dead

- AI: Make ally AI Spellmason follow you rather than pursuing enemies

- balance: Prevent cloning scrolls (I want to do something cooler with this in the future when you attempt to clone a scroll to reward players for being creative but for now I just have to prevent it because it totally breaks the balance of the game)

- UX: Improve explanation if server is behind in version
- UX: Add special message for when servers are down
