I have stopped using academymod for the time being. Don't get me wrong, I love the mod, just I hate some of the bugs.
On a side-note, in the next version could you remove the teleport effect? I don't mean the 'actual teleport feature', just the 'beam effect'. Reason is, is that it has been known to cause massive drops in framerate on my server.
Cheaters never win.
They just finish first...
