Well.. that explains how it happened....
that said, I don't think it should be the way it happens. For 150 coupon, getting beat up 9 times and losses only 270k coins is perfectly reasonable IMO, 90k is peanuts.
Thank you for your answer, but it would take a dev to know if this behavior is actually intended (that is to say if they purposely made that you can only get red once per day). The punishment does not seem to fit the crime if that was the case.
