Ranged promotion tree change. Garrison works also with forts. Coal power plant improved compared to previous GS builds. Before it was just 1 production. Now it's the same as the adjacency bonus of the district, which is amazing, as it rewards good IZ placement and it's also affected by the double adjacency bonus cards. Not sure if we had the factory one from GS, but it's definitely much better than the vanilla version when powered (5 vs 3).
