HearthCrawler is closed or hacked whatever it doesnt matter. Blizzard is banning people who use bots. Thats the reason HearthBuddy must go "stealth" That means bot actions have to get more human like ! Users need a config file to tweak the bot. And so on ....
As stated in many other posts. They are in the progress of creating hearthbuddy v2 which will most likely have alot more "human" movement.
