I have been trying to recruit a hero in my tavern and I am getting a failure message saying:Failure to recruit hero, unknown errors have cache. If restart the browser and clear its cache. If there are still any problems, please contact GM. So now I am doing so. It is very hard to get a purple and when you have chances and this happens it is extremly frustrating when you can't even recruit a hero because of some error. Please look into this and get it fixed please as it will be very difficult to play a game you can't get any new heroes on.
