I'm having problems with an elusive bug in my code. It's far too huge to post here, but basicly I'm trying to move the player, camera, and a good chunk of the world simultaneously a few units when the player moves from room to room. Sometimes when this is attempted, about once out of 20 times, the program will crash. If the debugger is up, it gives me the generic "Memory Access Violation" error during my call to RenderWorld(). Anyone have any ideas as to what might cause such a thing?
