Are you deleting the entities inside a callback form vphysics? e.g. VPhysicsCollision? That can cause crashes. There should be code that prevents that - i.e. UTIL_Remove() should actually add the object to a list by calling PhysCallbackRemove() but I don't have the SDK code in front of me so I can't check.
