Reproduction:
1. Load save _autosave-platform-6s-first-trip-to-aquilo : player sitting on platform
2. Try to switch to Nauvis surface
3. ...
4. PROFIT!!!! (crash

Switch to other platforms or planets works as normal.
Previously have this problem with first trip to Fulgora on version 2.0.10 (my 1s planet)
After bringing to planet problem is disappeared.
Current problem maybe disappear when i land on Aquilo.
For compare: _autosave3 without problem with surface switcing. Save on 2 minutes before bugged save.
