If I can make a suggestion:
When taking bars from the dispenser, the script will take out the bars and then close out the window, then it will click on the minimap to move to the bank chest. While it might not be anything to save time, (and I understand this is a goldfarming script), it might be beneficial to simply have it take the bars then click on the minimap at least some of the time. It's just one more thing to randomize the movements, and might cut down a second or so on each load. Just a thought Seems to be working pretty good with mirror mode, been running this about five hours a day for five days, no banhammer yet!
