As the title says. If pull 1 is the last pull in the list and then gets deleted, it returns an error. Doing this with mobs assigned can also lead to further errors. I caused this error on my default profile for Upper Kara, and now the whole preset is bugged and can't be deleted. Assuming I'll need to clear my saved variables for that default.
