You know how you get an ace and a ten (21) and the game goes directly to the dealer, puts his cards down, then you win or lose?
I'm getting this without having 21, it does not happen to often but still i lose every time it happens, now my luck is very high so it's not really a problem i am just wondering if other people have this.
I'm on PC btw.

Is the dealer the one getting the Ace and Ten/Jack/Queen/King? Because that's Blackjack... An automatic win unless the opponent has a Blackjack too.

Its not a bug, the game registers you hitting W twice (probably lag), i've had this happen to me too.
