Problem: Props keep randomly disappearing online.

So I play with my buddy on this basewars server, and sometimes randomly, every prop will disappear. Like not be deleted but we just can’t see them, even world props we can’t see like doors, ect. Sometimes right after this happens, my game just shuts down completely, and doesn’t say it wasn’t responding even. It happens for example when I pick a player up with my physgun, and like push them through a prop (I’m a moderator of the server) then sometimes everything will disappear, but not every time. Has anybody else had this issue? Please help me out!
