or something like that, can't recall the exact wording and have only two hours so can't view my Economy page.
Trying to expand RCs, I *sometimes* get that message. My first RC I could expand; my other two could not. I have tried in separate turns & separate turns from when built.
I have no idea if it is because of some actual game restriction or if that is just an error message that something internally is going wrong. (This is on Dwilight)
This is likely due to a brand-new update that changes how RCs are built.
Fixed now.
seems to be working normally now - was able to expand all my centers. haven't tried building anything new to see if that was part of the cause
