i used to have my mule on a different PC with a different IP , and the farm on a vps with different IP"s as well.
If you had your mule on the same server/PC as your farm then it probably got chain banned with the rest of the accounts
Not sure if it helps to reduce bans but could we have it so it drops the ores randomly? and not from left to right? like one time it would drop an ore that is in the middle then it would drop the one thats diagonal to it and so on randomly
