RimWorld Update v1.6.4543 Fixes Shuttle Landing Glitches and Adds Odyssey Credits Music

RimWorld update v1.6.4543 delivers the correct end credits track for Odyssey, resolves critical shuttle warp bugs, and fixes performance issues related to vacuum stats.

RimWorld update v1.6.4543 focuses on correcting visual and audio bugs introduced with recent content, alongside critical fixes for shuttle behavior.

Audio and Atmosphere

The end credits music for Odyssey plays the correct track. The music track Impermanent Waves functions as a non-combat song both on the planetary surface and in orbit.

Shuttle and Pathing Fixes

Quest shuttles do not attempt to land on water, which previously caused them to warp directly into player bases and destroy buildings. Dormant mechanoids do not block pawn paths, and pawns move more rapidly when pathing toward water for swimming.

Performance and Systems

The vacuum resistance stat is properly cached, resolving performance drops when numerous blueprints are active on a map. Gravship facilities situated on invalid substructures are marked as disconnected, and the game cleans up invalid scenario parts automatically upon loading a save.

Why this patch matters

This minor patch cleans up navigation errors for shuttles and restores intended audio cues for the Odyssey expansion.
