I farm 10 accounts 3-4 hours a day each account . I run in to a lot if bugie stuff . A thing that gets my account ban every time. when the Ore dose not fade away after looting it and my toon trys to loot it over and over. if your loot mines ore and nothing gets looted stop the bot and try to hand farm a few to see if they fade away or not. if your toon mines ore and gets nothing on 5 or so new mines relog the account and HB2 . if this dose not fix it log out for 30 min or you could get baned . i turned my "Blacklist a Node" setting to 5 sec to see if it would fix it and it did not. I have found 3 times where my toon starts mining over and over stoped botting for a few hours or went and sat in city for 30 mins.
