GE Mode works after a trip, you can't start the script at GE just yet. I highly recommend letting the script do a few runs and then GE mode will do the rest. However I am re-writing GE mode since it is still in beta mode and I haven't perfected it yet, I just wanted to make some experiments with code. Stay tuned. Next updates will be stamina (almost done with re-write) and GE mode.
Yep the script is working, just added a neat update for rune and gold ore too ^^ As for ROI, this script is amazing with making your money back + making ALOT more than you started with. Typically you get 2-3 days of pure blast furnace botting, first day being the break-even point
