Stainless steel - Can't construct buildings!

As the title says.

I am trying to play stainless steel. Everything works fine except for the fact that when I try to construct buildings and troops, it only works one round. When the building is finished, nothing happens if I try to construct something new.

It works if I exit to the menu and load the save again, but it'll be a chore to do that every other round.

Any solutions?
