When I place the following vehicle (from a new pack I'm working on, called 'AHP'), my game crashes. I've tried removing the sections where guns are declared (in the model and config). But in another model, where they are still present, it places fine. Further, when the AHP pack is loaded, the game crashes when I place a model (specifically my corvair) from a completely different pack, it also crashes the game. But when I remove the AHP pack, the corvair model works fine.
Furthermore, the model shows up in my hand just fine.
I'm also having the same exact problem with a plane.
