I just figured out one problem. Foul Weather Jack is something I did not thought to exist on 2nd Edition: Investment into future Advantage. The reason is that it gives character extra story thus extra experience. As GM I would simply fix this by either limiting the story to those stories altering but not advancing character. But I have better elegant solution:
Foul Weather Jack (3 points)
This advantage gives you Foul Weather Jack story which does not give you rewards, but Hero Points. The advantage also gives Hero Point when character advances any other story too.
