Not really an issue, but if you have items 'locked in place' for bank slots and there are no items left, script gets confused and just tries to withdraw something that isn't there. One account sat at the bank for like 45 minutes trying to withdraw, so probably will get banned lol. Not your fault, I should've made sure it had the items.
EDIT: This is a mirror mode bug, not the script. In-case anyone has the same issue.
