Are you serious?
I have been collecting the "sorcerers stone" while I already had an open "sorcerers stone" on my screen. I had received a "4 times" the amount of $money spent for the coins and rubies when both were in play. Now I can collect as many as I get, but there is no remedy for my only getting two times the purchases.
