RimWorld Update v1.6.4535 Addresses Odyssey Corner Exploits and Gravship Glitches

RimWorld update v1.6.4535 patches structural exploits involving room corners, prevents power scrambling during gravship launches, and fixes water-landing issues for player shuttles.

RimWorld update v1.6.4535 targets technical problems and exploit vectors related to the Odyssey expansion, focusing on structural boundaries, electrical systems, and navigation consistency.

Structural and Room Fixes

Several corner-related issues are resolved, preventing structures built through corners from altering room roles, turning beds into prisoner beds, or allowing enemies to ignite buildings from the outside. Diagonal walls do not leak room vacuum under specific conditions.

Gravship and Shuttle Adjustments

Gravship launches do not scramble power connections or reset flickable objects to powered states. The probability of gravship landing spots generating over deep water is reduced, and player shuttles are protected from being lost in water.

Balance and Tuning

The breathless gene suppresses the standard vacuum-resistant gene to eliminate its metabolic impact. Psilocap catatonic breakdown chance drops from 4 percent to 1 percent, and creative inspiration chance decreases from 2 percent. Gravcores are removed from trade request requirements.

Why this patch matters

Update v1.6.4535 closes exploitable geometry gaps and stabilizes gravship launch procedures for late-game colonies.
