Already emptied the cache directory, and now that you say it, yeah, we're using a fastdl which is not updated. I can't update it right now but I sure will.
I updated TTT today on my server, rebooted it... and now instead of the gamemode, here's what happen :
I tried rolling back to an older version, deleting some useless junk in the addons folder, deleting useless gamemodes on the gamemodes folder... still happens. Everything worked fine before, but now, trying to get back to the old version we were using still does this. Anyone mind helping me? :(
