Hi, whenever we restart the server we get a big
error with an internal error command. When
trying to join any lobby we setup within the
Quake plugin.
Error: http://pastebin.com/5g2KdEXf
Thank you. Whenever we set it up, and restart,
we try to join, internal error, it says we joined
(then error) and we can't leave without exiting
the game.
TY please resolve!

To fix this annoying thing, I have to replace the config folder, and do /quake reload. When the server starts.

After a couple of config resets after launch, the issue fixed itself. But I think other people could be having this error, and there is something wrong with the plugin that did this (must've). This error will probably come back once I start a second arena,I'll let you know.
