Orange flashing pop counter on cheat code

[Langbart]

to reproduce

• start a map with a civ of your own choice
• enter gift from the gods
• select CC and enter salad bowl 200
  • You may have to run the command twice for civs with a large CC like Han/Ptol/Maur
• notice the pop counter blinks orange
• delete all units, it still flashes
• it only stops when producing a new unit
• minimal replay (~1min)
  • attachment:commands.txt​

reproducible

• does not occur in A25b
• starts to occur with A26
