I just opened the game last night and found that all of my maps were locked. It looks like all of the city data is still there, but if I open one, it treats it like a new city and I have to start from a city level of 0 again
I'm on version 1.9.51a, and I just installed the Modular SLC Warehouse pack, Escola Brasileira, and Gama Tower.
Anyone else having this issue, and is there any way to get my city levels back?
