I just can’t get this bot to do more than 2 chests before it bugs out. It just can't accept the option to enter the tunnel and stands clicking and teleing out and coming back to the same room and sipping prayer doses.
Edit: I figured it out. I spoke to the old man at barrows previously to shorten the tomb message in-game and it seems I needed to revert back to the original 2 screen dialogue for the script to recognise there was no brother in the tomb.
