Yooo your map 4.2p is not good! Like trigger wise! There's a bunch of lag in it and I can help you!! PM me back and I'll walk you through preloading and memory leaks. Also, the game crashed when I was going upstairs shooting the zombie, but the crash may have occured elsewhere, not necessarily by me. Anyways, PM me so I can help you!!! Memory Leaks and Preloading! trust me I just KNOW that's it =D.
