Summary
Gameplay & Performance Improvements
This update for RimWorld addresses several critical bugs that could lead to base destruction or data loss. Most notably, quest shuttles have been restricted from landing on water, preventing a bug where they would teleport into and destroy player buildings. Performance has been significantly improved for maps with many blueprints by properly caching the vacuum resistance stat.
Combat & Content Adjustments
Combat mechanics receive a notable fix as the RangedWeapon_WarmupMultiplier stat is now correctly applied to pawns. Additionally, the Odyssey ending features a new epic music track, and various faction and quest generation bugs—including issues with the Archonexus and Gravship scenarios—have been resolved.
