Dears,
I built barracks in double resource provinces to produce troops faster, and after few days I recognized that the speed is the same as single resource provinces. The morales is same so it's not the problem of morale. I checked with other players, and they haven't seen such a problem. Does anyone have a clue on this? you can see that in a picture, morale is 100, but instead of 8 hours, it's 16 hours.
