Works great now. But after 55mins it stopped while all process finished, but there where still ~8k left. I'll will check if it does it again.
EDIT: Same happened after 12mins. This time i set the target for 10k.
Having a problem with running it on RS3, after the start it withdraws all the items and starts to click on magic shieldbows to string it but nothing happens. Only the mouse is moving in the inventory.
