In my opinion if this glitch is being made intentionally of a certain guy inside to earn by this opportunity. And the management does not know about this. Maybe it was running for a long time. Probably??
This is a very interesting possibility and one that may be true, if one of the people working at the casino notice a bug like this one and instead of trying to fix it they could try to take advantage of it, and even if it is reported if they are the one is working to try to keep the website out of errors they could always claim that they found nothing and everything is fine and keep cashing out profits this way, that would be a very dishonest thing to do but we know that scammers to do really care about it.
