The log fletching is FLAWLESSSSSS. The stringing, is horrible. Sometimes it withdraws the correct supplies, 14 bows (u) and 14 bow strings, then I'm assuming it thinks the bank is closed and hovers over a bow string but the "use" message at the top of the screen doesn't appear because it's in the bank and the option is "deposit". I don't know how creating a bot works, but I'm assuming that's the problem.
You go to the store and get it for free. All the scripts are there. Some are free, some not. This one does happen to be free. Purchase it, which really means nothing because it's free, then open the client up, sign into your account, and it will be there.
