my plane cloned itself in the past so i was flying a past instance of my plane, which i landed next to the instance of my plane that i was flying before it clone itself, then when i reloaded the past instance of my plane plane dissapeared, which i was controlling, and i got this popup. i was mid flight when it got cloned.

Heh. What happened directly before this? Did you anchor the tech you were piloting there somehow? Is there still a cab on it? (I'm oddly interested in TT bugs.)
