The reyka crash and the the doubled text are known issues now and will be fixed in the next patch.
The team match stuff is still considered relatively unstable, and I probably wont be merging that into master for the next patch.
leveldrainer itself prevents exp, since the original purpose for that was to make it so that you *had* to drain levels to level up. The problem with level drain right now is that you gain the exp, but it never checks whether you should actually level afterwards. I fixed this in the latest version.
