If you force or attack the fairness system and receive two server seeds, one of them revealed, then the system no longer knows what result to give. It gets completely disrupted, and errors may occur, just like in any system that is breached. We don't have ability to manipulate the results, because they are based on a server seed and can be checked.
Just to be clear, I believe what OP did was wrong. If you find a bug or vulnerability in a system, the right thing to do is report it to the casino's owners or the deve team so they can fix it, rather than trying to exploit it.
You are saying that when there are two seeds, like in this case, the system doesn’t know what result to give, but according to the screenshots and videos posted by OP, it appears the system will make sure you will lose no matter what!
I hope you will fix this vulnerability, asap.
