Today I tried joining the server while the map was Hotwireslum, and it kept giving me an error saying that a file wasn't retrieved or downloaded properly. The file was the the name of the map and ended with .bsp. Then when the map changed to community bowling all the detectives were just the big red error models. I just uninstalled all my downloaded mods and verified my steam files and I'm still having the same issues. I just tried to re-join while the map was on portals and I'm getting the same error.
