Very stable. Has a few things that could be improved:
1. Sometimes when right clicking the GE bankers, it will scroll through the menu with the cursor and "exit" at the bottom.
Then sometimes it attempts to right clicks again and succeeds.
Other times it will left click.
I think the right click feature is probably meant as antiban, however a legit player would not "exit" the menu once or twice before "succeeding" :-) This script does that most times it right clicks from my experience.
Personally I would always just left click the banker if playing legit.
2. Performance wise, you could probably get slightly more bows made per hour if the bot "prepares" for inventory completion. For example, "when 1-2 items left" -> "begin to move cursor towards banker.".
I really love the "queue" feature for training up from level 1 fletching with various tier items.
