Mini Update (Version 0.163)

Calculation of loot grades has been fixed so that having "Find Rare Chance" no longer lowers your chance of finding Elites or Uniques
You no longer need to talk to the mission giver to find missing NPCs
Kick no longer defaults to left click to prevent accidental kicking when firing a weapon
Sneak Visibility no longer stacks with Visibility, meaning you can no longer be completely invisible to zombies
Default visibility and hearing ranges have been increased by 60%
A bug that stopped your EXP being saved when visiting an outpost has been fixed
Fixed a bug that caused too many zombies to spawn in the Open World, and caused them to get stuck running in circles
Fixed a bug that caused all outdoor enemies to run when leaving Comer and Son
You can now change controls AND play in DX9 mode (see Steam launch options)
A bug that stopped chainsaw cosmetics from being previewed has been fixed
You no longer lose stamina while holding shift and aiming

NOTE: You will need to quit the game client and install the update on Steam before theses changes take effect. If the game fails to update, logging out of Steam and back in again usually does the trick.
