Maybe i'm just missing something ... I checked my city to see if i had enough health available to build a coal powerplant (it was 27 health, 25 unhealthy). A powerplant adds +2 unhealthy to your city. So i built it. Turn after it gets completed i got 27 health faces, and 29 unhealthy. When i mouse over the health icons, it says +4 unhealthiness for power. Population didn't increase and neither did anything else change. Powerplant was built in 1 turn. So i went to my other cities which already had coal powerplants and they all say +4 unhealthiness for power. Soo... is this a bug or am i missing some important aspect that says i get an additional +2 unhealthiness based on some obscure fact? RUnning BTS with latest patch and the only mod is DCM.
