@maddbuddha I've received an update from our developers. They believe they've fixed this issue and the changes should be live with the next playtest. Please let us know if you encounter this issue again.
According to our Dev team, they are aware of this issue. They informed us that when you purchase a new character, even though your total may say 0 it is being tracked, this will resolve itself and update to the correct coin amount. If after purchasing a new character it doesn't work, let us know so we can update our Dev team on this issue!
