I went to the coin shop to turn my 100M bags back into coins, I had 13 of them and so went to the store and clicked the option of 'Sell 10'. Despite only having the bags and the rest of my gold in my inventory I was given the message saying I didn't have enough space. It then deleted 10 of my 100M bags and didn't add the cash to my already existing pile...
If anyone could help with this to get the money back I would be very grateful, thanks.
