With English it works but not with Guldan and Illidan. It says Book of Heroes is completed (but it is not). I have the latest version.
Anyway - bot still have problems with winning with some opponents, fighting like 10-20 times without success. I don't know if it is possible, but some bosses can be defeated just doing certain actions. E.g. against Monkey King (Anduin story) you just drop Cleric 1st turn, Power Word: Shield 2nd turn and Divine Spirit + Inner Fire 3rd turn - thats it, than you play normal and win easily. Some other bosses has similar things. Can it be hard-codded into bot?
