RimWorld — Update 1.6.4528 released

Hello! It’s been almost 2 weeks since Odyssey came out, and we’ve been hard at work fixing bugs and incorporating your feedback. If you’d like to help us by reporting a bug, please join the official RimWorld development Discord.

Today’s update has improvements and fixes for RimWorld, Odyssey, and the other expansions. This includes things like removing the -3 soaking wet thought when swimming for recreation and reducing memory usage overall.

This update should be compatible with all savegames and mods.

P.S. Send us your gravships on X or BlueSky by mentioning the @LudeonStudios account!
