I know I shouldn't be bringing up a thread this old, but it's struck again.
This time it's in Inferno R1, in a self-made quickie mission where the player has to shoot down a Gigas

. The moment I press the external view camera button (or jump out) while flying the SOB Artemis Adv, BANG! Crash.
I tried running a debug build but all I'm getting is lame errors about the Gigas missing a load of subsystems, and I can't bypass them. I tried a TBM with the bad entries removed but I'm still getting t3h error as shown in the code box below. Deleting the cache folder didn't work either. -_-||

below is the error caused by the Gigas problem, not the actual problem I'm after [which is the game crashing when going into external view, or jumping out, while flying certain ships]... (Bangwal)
