I don't know if this has been addressed yet, but sometimes the bot hovers over the rock, but doesn't mine it. Is this part of an antiban feature, or is my script just messing up?
I also run into another problem similar to the above one. Sometimes when dropping ores, it will miss the "drop" tab and accidently click on an ore. It stops trying to drop ores then, and goes back to the rock, but it doesn't start mining. It just hovers over the rock. In the top left corner, the option is there to use the iron ore on the rock, as the ore is still selected.
Other than that, it seems to work.
