Let me play devil's advocate and reverse the perspective : if the slot machine had a glitch that caused players to lose much more than their expected value would Nevada gaming and Fed taken the steps to identify and refund them for the money lost, for the emotional damage due to negative feelings unjustly felt while living that negative experience caused by the glitch and the for time they wasted?

https://www.americancasinoguide.com/info/are-slot-machines-honest?The gambling commission is in charge of casinos and their regulations, if you want to go and recover eventual losses from that, you have to opena civil lawsuit, the gambling commission can't rule on law, it acts on it, only a judge would be able to give a verdict just as a judge did in the above case.
The order is in reverse here, it was first a criminal case that was dismissed, just as police are forced to come to your house if there is 112 call claiming people are getting shot there and investigate if they indeed find bullets. It will only be the judge who can find you guilty of the shooting or not.
