Ok, I don't know where else to put this, as this is a custom model related error, but it's probably related to FSO and PCS2 as well.
I've found that on certain ships that I have, if you run into (as in, collide a fighter with) a certain destroyable subsystem (or turret), the game will just hang, then crash a split second before the collision is to occur (without actually playing the collision sound).
I'm not sure exactly what causes this to happen however. I do know that I experience this on the big turrets on a reskinned Trashman's GVI Abythys (or whatever, its the big round-ish vasudan installation), and the any of the cargo pods on a reskinned GTFr Demeter.
I could provide the models and the table if needed.
Does anyone have any clue whatsoever on how to fix this issue? It's holding up a few (ok, two) in-development campaigns I have.
