While trying to fly offline, I switched terrains, to mindanao. When I hit fly, CTD. Then, every time I went to hit offline, It would not even start. So, I found that if I go into the terrain folder and manually edit curterr to "akdesert" it lets me fly again. My questions are, does this happen to others, and how many terrains are not going to work? Is there something I am missing in this? Just thought you should know if your having the same troubles. Obviously a bug.
