It works, the character stays in place and you can right-click and the mining continues. The problem is not emptying any ores. Not a viable option to leave running overnight.
I have a feeling, like with the Pick Up All setting, it automatically unloads all inventory items from the bottom 5 rows. So if you turned on Pick Up All, the bot shouldnt move if anything is dropped around you anyway since settings are 0. But once your inventory gets to last to full slot, it will automatically dump items...
The question is normally the bot will run around randomly because it knows the ground can only take so many items (9 around you). So...would the bot make the same move if settings are on 0/0? Probably. And then the question of dropping the gems...
