Been running it for multiple hours and it's gotten stuck on the way back 3-4 times. It keeps clicking on the side of the entrance and is unable to see the bankers, thus making it keep searching and searching. I had to keep interrupt it to move it a bit so it could see the bankers and then it'd go back to running smoothly. Perhaps do a safe check there that after 5 times not being able to find the banker that it clicks on the minimap again so it can see the bankers, otherwise it'll get stuck for hours on end doing nothing.
Also, when softening, it sometimes runs back without softening the full inventory (leaving 1-3 blank and returning to bank them).
~A moment's diversion may amuse an audience, but it changes nothing.
