I didn't get a refund and I purchased several Brain Capacity cards. Now I'm not certain how much iMG I spent on them. Will all erroneously priced cards be refunded, or do you have to spot and report them?
Botsy, the refunds take some time and start from the oldest accounts first. If you joined relatively recently, it might be awhile before your account is processed.
ThursdayNext, you have over 50 brain capacity now, and the new price for Brain Capacity +1 upgrades after 50 brain capacity is 80,000 iMG.
Chichikova, you'll need to wait for your refund first before reshuffling to get the updated prices. Since you're still at 50 brain capacity, the old card prices were 160,000 iMG.
One way to check how much you have spent on brain capacity is look at your upgrades page and it will show how much you spent on the cards. Also, once they do the refund they will send you an in game mail message to let you know it was done. And yes, as others have said, probably best to wait to upgrade further until after this is done for your account.
