Perhaps they void all of your bets after the "payout error" drama?
That might happen if they consider that you place bets with the money/profit from the payout error.
Perhaps that's what happened. If OP wrongly won 10x more than they should have and then played with that money and won other bets, they could all be considered void unfortunately.
@elegigglebets
Can you post a screenshot of all your betting history so that the public can see the outcomes and how your balance moved up and down with each bet?
Also, how many bets did you place with the money you won from the wrongly settled 10x bet until Wintomato removed a part of your balance?
