I botted all night last night without any issue. This morning I saw there was an update to the bot, so I updated. Now the bot won't attach to WoW. It says that it's an invalid instance, and that it only supports instance #16057 even though it continues to say that I am on build #16057... I re-downloaded the bot to no avail. Ignore the whole authentication failed part, I re-downloaded and I couldn't remember my password at first. Edit: I've gotten it to work again by simply restarting WoW and the bot half a dozen times, but I'd love to know if anyone has a more concrete solution the this problem.
