I'm actually running into crashes to desktop (the Freespace has stop responding kind of error) and debug catches absolutely nothing. It happens specifically when I select certain models first.
For example, if I try to load the Ulysses first I get a crash. But when I load a terran container first, and then select the Ulysses after, no crash happens and the model loads properly. I don't really any any leads on what it might be, I can load an Aten on first try for example, but a Seth or Tauret crash.
Also +1 for default pitch and yaw instead of no rotation
