Works flawlessly. I like the set offset value to make it appear more human and less like a bot. It gives a random time to "tune" the harp instead of right at the number you set. Usually about 10% to 30% lower than the number you set. This bot has given me lots of harmonic dust while I watch a movie.
This is completely flawless. After running it from 75-99 crafting, I am yet to see an error. I've run this bot for over 10 hour instances without any problems or bans; all in all, very well done to Derk! And thanks for the levels <3
