Had been on a planet building a base. I notice the game freezes on occasion (not frequent, but consistent when it does) indicating something likely being generated out there somewhere. Note if there's any way you can get spawn logic off the main thread that may minimize or eliminate most of that type of freeze.

However given the above, no actual crashes had happened. Just the occasional freeze while planet side working.

After leaving the planet to continue working on my ship outside of gravity I saw a CIVL freighter appear about 10k out. It roamed around a bit then vanished.

Continuing to work on my ship the game froze for a bit, so I figured the mod is loading objects, doing whatever calculations etc. Instead of it unfreezing, it popped to the desktop in a classic CTD.
