Weird map crash

So, i’m using rp_downtown_v2_fiend_v2b on my server, an old classic, however i’m getting a very weird bug. When I join the server right after starting the game (not loading any other maps before then.) I instantly crash. However, if i load any map BEFORE i join, it loads successfully. Same goes for other players. Same thing in single player too.

Any ideas/fixes?
