It is unpleasant to see a typo on a serious site. It is even more unpleasant if this typo makes you nervous.
However, as we saw, the site can't be called a Scam and the hash they have matched.
Perhaps they should have paid more substantial compensation for the error found and the disturbance caused. It's on their conscience.
I'm not sure about that. They are now clearly aware of the so-called typo but they still haven't fixed it...
If an user is unable to check the fairness of the game with the datas provided by the house, it's a scam to call it a provably fair game.
