You're not the first one. One of my members have mentioned it to me. I think it took him a day to upgrade to Enlightenment Age. Must be some type of a bug/glitch.
Lol this age rush seem to misconcept some people cause it simultaneously runs for 2 ages at the same time
The key is when it says, ''X town center upgrade is instant...'' it means the upgrade to that ''X'' town center from previous age is instant!
Yes, this S.o.A. is pretty weak compared to prior Ages events. The 30% production boost doesn't even keep up with the increased activity levels, so the economy seems to be at roughly the same level it would be after consecutive weeks of big sales. I guess the idea is that the museum is supposed to make up for it. Personally, I'm not seeing it across my accounts.
this week is the instant upgrade to go from medieval to enlightenment. next week is when you can instantly upgrade to industrial from enlightenment. it definitely is very confusing
