the reason workers disapear is because !people die! and blue prints dissapear because when you go to a new town it has set lvls and blueprints you can't transfer stuff it sucks and he shoud probably fix it but no reason to get pissed cause you suck at the game.
great game i love it but a few glitches if you do somthing early in the game you cant open the hibernation chambers so look into that other words a good 5\5
