So I rarely build forts the old fashioned way (4 guns and 4 supply elements), and I was surprised to see that I couldn't expand a current fort. For clarity, Washington DC, in the April 61 game. You get a fort automatically via an in-game event, but it is only a level 1 fort, which has a an overcrowding limit of 25 (and the event generated garrison is bigger than that.) Upping it to 2 would up the limit to 50. The problem is that I can't seem to do it once the level 1 fort is there. Is this normal?
