It adds a new ending song for Odyssey, stops quest shuttles from landing on water, and delivers a notable performance fix for blueprint-heavy maps. Compatible with all savegames and mods.</p> <h2>What's New in RimWorld 1.6.4543</h2> <ul> <li><strong>New Odyssey ending song:</strong> the end credits now play the correct, epic track — a nice reward for players who reached the expansion's ending.</li> <li><strong>Quest shuttles no longer land on water:</strong> previously, shuttles could attempt a water landing and warp into your base, destroying buildings in the process.</li> <li><strong>"Impermanent Waves" reclassified:</strong> this music track now plays as a non-combat song on the planet and in orbit.</li> <li><strong>Swimming pathing:</strong> pawns now move more rapidly when pathing to water to go swimming.</li> </ul> <h2>Key Fixes for Odyssey Players</h2> <ul> <li><strong>Royalty shuttles</strong> can no longer land on unsuitable terrain and lose their contents.</li> <li><strong>Psychic drones/soothes</strong> now affect space maps correctly.</li> <li><strong>Gravship wreckage quests</strong> can now generate after archonexus when using a gravship scenario.</li> <li><strong>Dryads</strong> are no longer deleted if taken on a gravship without their gauranlen tree.</li> <li><strong>Vacuum overlay</strong> updates correctly after gravship takeoff.</li> <li><strong>Torrential rain</strong> no longer floods through bridges.</li> </ul> <h2>Performance &amp; Mod Compatibility</h2> <p>The most impactful fix is the <strong>vacuum resistance stat caching</strong>: it was not being cached, which caused significant performance issues on maps with lots of blueprints. Ludeon also fixed modded sound loading on Linux (paths containing spaces), corpse item search, and the <code>RangedWeapon_WarmupMultiplier</code> stat that was not actually being applied. As with all recent 1.6 patches, this update is <strong>compatible with existing savegames and mods</strong>.</p>
