[R&F] Leader ability modifier not work with city requirement

[TzeLust]

I want to make a leader ability that will remove loyalty per turn for cities that match the requirement. I'm assigning a requirement that has the class "city" marked. Nothing works. I assign a requirement that has the "player" class - everything works. The code:
