I noticed that after zulrah is dead, just before the loot becomes visible the bot will rub the ring of dueling every time, and THEN go for the loot and then rub again to tele out. Also notice the bot struggles to collect items after dying. It basically runs around the island for a bit but doesnt't go to the princess to collect the items.
Edit: The ring of dueling pre tele rub appears to only be an issue on mirror mode.
