I guess Sebastian said that because those buildings were obtained by spending real cash, not earned in some way... but as Ivan also said, the change occurred almost 5 years ago. that gave some time for getting the full return on their investment i guess... but i'll miss those 10 planetariums to visit with an active friend in needIf I sell one my redundant buildings (which I have plenty of), I get a measly amount in coins and have to wait the full re-building time when I replace the sold building with one of my warehouse-buildings. Why should any other situation be rewarded greenies? Let alone 100 each?
