Hey
I'm having the same issue, set up numerous scouting assignments but after a short period of time they will duplicate, and when I go to delete the duplicates they remove ones either above or below. For some reason, scouts are also unassigned to the assignments i set them (all are ongoing so should not be unassigned) randomly. I have no idea what's causing it but have attached a few save files showing the progress of the issue (at no point between saves have I changed the assignments or reassigned scouts).
