Is it only the Europa base that this happens to?
I got to NaNSpace while trying a ballistic trajectory from UMmu Demo base on the Moon to Brighton Beach. At first everything ran fine. Then, while braking (I was quite close to landing) I decided to switch to a ground camera view. I paused the sim, placed the camera and then un-paused. I could see the Glider getting out of control with Lola trying to correct this, then everything went nuts and I got into NaNSpace.
NaNSpace?
