When i switch bsps from the first to second one I immediately exception. This happens when I enter the trigger volume in-game. I can switch bsps perfectly in sapien. Andy so, since the only difference between Sapien and ingame is that there are no AI in Sapien, I'm assuming it's something to do with my AI in the second BSP. I had a problem like this before, where my camo jackals would crash sapien when onscreen, so I'm assuming it's the camo elites I placed in my second BSP. BUT in-game, if I use switch_bsp and then fly around in debug, I can fly normally until I look in a certain spot, which again, i'm assuming is the second bsp. The only thing is, the camo elites aren't spawned by switching the bsps, and there's nothing suspicious I can think of in the second bsp that is spawned immediately at the switch and would be causing the exception.
Also, please excuse my grammar, I typed this out in 5 minutes before I rushed out the door to school.

did you try removing all of your AI and testing?

I just eliminated the second BSP from my map. No more exceptions, although, I do have another problem, I have an encounter of 10 grunts and 8 elites, and when they spawn, they just stand there frozen. Not even playing the idle animation, just frozen. If I kill them they will drop weapons, but they wont animate.

Put a camera point overlooking them. Name it something. Then, add this into your script:

(object_pvs_set_camera [name of camera])
