i do have the cue. but everything builds at the same time independently of the other so my iron mine should finish before my fort not take the same time as my fort.
Please read descriptions. it doesnt build simultaniusly, but 1 after another. it just counts time simultaniusly. you start 2 buildings. 1 needs 60 min and another 2 min. so first will finish in 60 min and another 2 min later. if you start 2 min building before, it will be done in 2 min, but another in next 60 min. time adds up. You can build only 1 building, but queue allows to put 3 aditional to start after previous finish. just so you dont need to come and click 4 times.
