I cannot earn any koins and I have been grinding them. Tells me I earned x amount of koins but they never show up. No I don't have an augment changing them to hearts either I have seen this is some kind of bug from researching others. Trying my shot and seeing if anyone knows a fix or if this will ever get fixed because the krypt is bascially useless. I know MK1 is around the corner and I highly doubt they will fix this now. But we paid money for this game! I think its not too hard to fix sometimes bugs because there is a many people with this problem. And i send them many tickets for this but no one answer it. Bad customer support!!!
