Alright so I found a bug that's rather.. abusable, I picked up the x-bow crate then a random weapon drop appeared, I picked that up thinking it'd wipe the x-bow instead it overwrites it, replaces it and then spams your screen with a dvar warning about being unable to write the weapon, then...

What ever you did to your map, you pretty much killed it. Texture tearing, obscenely low FPS which was NOT present in the old release, oh and crashing for no reason. GG fix or kill the project.
