Prometheus Tower


I have Apollo Gate Level3 and 1 built 1 Prometheus Tower and says 1/2 in the Tower Overview. If i try to build a 2nd Prometheus Tower it will be rejected as I need Apollo Gate Level4.

Is there a bug or do I do something wrong?


The Gate of Apollo determines how many towers you are allowed to have in total. If you want a second Prometheus, you either have to upgrade the gate so that you can have more towers or remove some other tower to make space for the new one.
