There are now no more known show-stopper issues or bugs left in Foundation.
I still need to redesign the buildings a bit to make more sense (And actually work) in the new City/District mechanic, and change some resources around.
But don't worry, I won't spend too much time "perfecting" this, easy to change in a future patch.
As soon as I have a definitive ETA I will set the countdown.
Very soon now the months of work will pay off and I can finally move on to more exciting things than checking bugs off a list!
