Contact IGG via service center and send them this screenshot.
Another bug that I have encountered on stall. Take care and pay attention to your load when you buy stuff from a stall,I bought around 4k FIO and i wasnt paying attention to my load,i chose the max ammount and i purchased em. I lost around 400kk and I got about 126 FIO,the seller was a friend of mine,he said that his FIO dissapeared. I contacted IGG about the problem and they didnt offer any refounds saying that they did not record any loss that day.
