I don't know what it is, but it seems Garry's Mod doesn't want to download any bsp.bz2 files from any server. I've been having this issue with CerealBox as well (seems to work fine with Murder servers, for some reason). Can someone just provide me the file "Maps/theater_yuki_v1_5_2c.bsp.bz2" and tell me where to dump it into my Gmod folder? One idea - maybe provide the Yuki Theater files somewhere so people who may have DLing problems can download the files directly at any time. You can just use Google Drive or something to host it if need be. Thanks.
