yeah its deffo not intended and does need some tightening up. I think the main question is how to use/resolve debts with fellow PCs and how that interacts with other moves.
I'm sure something will come up, but I just gotta sleep on it enough.
I've run into this question myself with my own playtesting. It's on my list of things to update or add in the near future but right now I'm just not sure how to handle it since I forgot to really anticipate PCs being at odds with one another.
