I have 5 cities. 9 health from difficulty, 6+6+6+5+5 from buildings, should make 37 in total. The screen only counts 31. The problem is, before I got health bonus quest for buildings, I got +2 health as stated. After Making it +3 health, I get 0 health or 1 health when I *purchase* the buildings. Constructed buildings work just fine. What's going on? Anyone have similar issues?
