Now happened at FlyTampa airport with a custom config and GSX was deboarding. I departed from this airport, without having services except pushback, departed and landed at another airport, requested deboarding, boarding, and pushback. Now come back and landed, requested deboarding and in the middle of deboarding quit p3d. P3D hangs taking longer to quit, a prepar3d.cfg.txt is created and dxdiag.txt with the same errors.
