Just started the script encountered problems straight away; It took three restarts of the script before it even started mining, It got half an inventory full then it got stuck infront of a rockfall I waited ten minutes before clearing it myself, It got an inventory full, cleaned the ore, emptied the bag into my inventory then the script stopped and didn't bank. Overall I think the script is an excellent idea but it needs a lot of work on it before it goes P2P. Thanks and well done Toda.
EDIT: I have also just encountered this issue too as you can see it has been running fithteen minutes and I havn't mined all of that ore.
