Ostranauts Hotfix 0.15.0.18 Resolves Station Docking and NAV Bugs

Ostranauts hotfix 0.15.0.18 tackles multiple reported bugs from the Fire in the Hold update. Fixes target instant station asphyxiation during secondary ship docking, invisible NAV orbits, and character creation null exceptions.

Ostranauts hotfix 0.15.0.18 is available, addressing critical issues reported by players following the Fire in the Hold update. Saves started in version 0.15.0.0 and later remain compatible.

Docking and Station Fixes

Docking a ship to a space station while another player ship is already docked no longer results in instant suffocation. Several null reference issues in the NAV and Docking/COMMS UIs have also been resolved.

UI and Navigation Corrections

NAV station orbits are visible again. The hallway conduit tutorial no longer breaks if players leave and return to the map mid-tutorial.

Character Creation and Stability

Extensively utilizing and then undoing changes in the skills and traits section of character creation no longer triggers a null error. Particles generated during gas exchanges no longer cause null exceptions, and a missing encounter that caused the Ceres plot to end abruptly has been fixed.

Why this patch matters

Hotfix 0.15.0.18 targets essential stability and navigation bugs introduced in the Fire in the Hold update, making multi-ship docking and character setup reliable.
