Thanks figured it out by now… still am collecting loads of DNA, which indeed takes a lot of time. Read here somewhere that houses give DNA not people… Good tip! I found out another trick: kick one person out of your mine, temple, brewery … wait a minute, than look at all awaiting people in the game and sent them manually to that place. The more you send (untill the first one fills in that ampty spot) the more are assigned to that building, which gives you the things you need faster :)
