Great botting script!!
Sadly, I've come across a minor bug which occurs when yew tree farming in south-east Falador due to rendering distances. Whenever you finish cutting the yew tree furthest east the camera turns and then try's to click on the yew tree to the west of that tree..... However, because you cannot see the yew tree rendered in, it is unable to click on it.... so it hovers there until the yew tree you're standing by respawns, at which point it click on that and continues chopping....
tree.notree_noarea 1004
tree.notree_noarea 10042
Here's the console errors if you wish to see.
