I do have something to ask of the developers.
When you upgrade a base structure, (say from a Gas Plant to an IT Center), the little mini screen pops up and says, "Congratulations! You upgraded to a GAS PLANT, (instead of the new structure), share the news with your friends!"
I've ignored it for the most part, but there have been times when I've been tired and that mini screen pops up and I freak out thinking I repurchased the old structure type instead of the new one.
You all may want to look into this and make certain it asks that you want to brag about the CORRECT structure, (i.e. the new one), instead of the old one.
