Hello,
Indeed, Blizzard have added new method for detect bot, this method is destined a another bot, and can affect some others bots.
This checks from where is called the wow function named lua_load, and I do not use this function with WRobot.
WRobot is not affected by this, if there is a known risk I stop wrobot auth server directly (this close automaticly your bot).
But don't forget, botting is dangerous for your wow account, I recommand to not bot on your main account, mainly currently.
