We are in the process of laying out where type1 and type2 can be built for each faction. We hope to have the new maps and placements ready by the next patch.

But as to why it wanted you to build a new core building, I've no idea. That sounds really weird. Govts shouldn't be allowing the construction of a new core. So you are saying that now you have two core buildings in one province? And that you built one of them yourself?
