Are building supposed to get done faster if I set the game to 2x and then leave it running for awhile in the background or not? I had my villagers working on one of the buildings and it was like 59 percent complete so I set my game to 2x and let it run in the background and when I came back I noticed my food had gone down like normal and I had way more tech points then before but the building was still at 59 percent.... Is this normal?
