Problem with building queue

[Hajuta]

My building queue keeps cancelling my 3. build order, even that I have necessary building materials and licences. Anyone else experiencing this problem?

It happens.
If your working your last couple of lisences the game will not alow you to set em all at same time , you can however fill it up with wheatfileds/wells etc.
You can still use the lisences, but you need to wait till the buildingque finishes a production building before you can add next.
