So after the new city plan pack of the contest plans was updated with the Hangmans and Jamaicas plans, some leaders, Preston and Sturges that I have noticed now, have been unassigned from their post. When I return to their assigned settlements a notice pops up that for example Preston has been assigned as the leader and then scrap settlement popup comes and as I say Yes(plan has been unselected as well), it scraps the settlement and builds a new one. It only affected some that I have seen but it still is weird and annoying, as all the progress that has gone into cities upgrade goes with this issue. I hope it does not persist.
