TouchMeGently, there are a few people experiencing this problem (including me), and it seems they are all Koreans (or at least have to do with some other foreign language, i'm assuming).
There's no use asking the mods about this problem, because they don't seem to have a clue about this particular question.....yea there have been several other posts made with no solution.
Anyways, make sure the toon you're botting with has absolutely zero foreign language chat. If someone, or you, types or sees any foreign letters, etc, then just exit wow and restart.
With your chat clean of any of that, your bot should work fine.
