if you have an inventory of paydirt that hasnt been cleaned yet (the machine is broken and the dirt hasnt reached the sack) if you go to load the sack with a second full inventory before the first inventory of dirt has reached the sack, it won't let you load the ore in the hopper, therefore the bot goes to pick up a hammer with a full inventory of paydirt and isn't able to grab the hammer because its inventory is full with paydirt already so it tries to loot the crate over and over failing to get the hammer. just letting you know
