Collision error...

[Gothamite]

I'm having projectile collision errors...
The problem is that in certain areas projectiles go right through the collision bsp, but other objects don't.
The map compiled without errors, and I didn't use tool** so I dont know whats wrong.
Also vehicles often get stuck in these areas.

I've obviosly never had this problem before so any help would be nice .

glitch/bug, not error.

vehicles get stuck, projectiles and equipment go right through, bipeds are fine(or so it seems).

Are all the collision types set right in tags?
