Couple things I noticed.
The slayer task was Lizardman and when it teleported to Farming Guild it just stood there, didn't try to open anything. Once I manually opened the door it started moving to where it needed to go.
For spiritual rangers, it changed all my gear but stayed at the bank and didn't even attempt to go towards GWD.
This bot works pretty well. Definitely would advise to monitor it here and there and not bot too long. The normal sane person can't do pest control for hours straight.
Hey Czar, I don't know if it's part of your script build but usually when its getting a full invent and then dropping it will try to mine one more ore after being full and then drop. Kinda repetitive I feel
