Hello! While I was playing this map (amazing map btw), I continued to walk towards the stairs where the black zombie will appear. The only problem is when it starts moving (I can see the right arm move to the left), my game crashes.

First, no. It isn't because of my PC. I googled it and realised that it has happened to multiple people and not just me. I tried using it on my Garry's Mod server as well, but instead it crashed my game and it said I "timed out".

I tried searching for a fix but I can't find any. Does anyone know how to fix this?
