Your own cards might stay unrevealed
The sign above the poker table can sometimes fail to change to it’s more descriptive state (the one listing minimal bets, among other things)
Raising is completely broken on some tables at times (take the min. bet 100 one for example. The only amount I can raise is 100, even though the counter always says it’s 20. Only rarely, if I fiddle with the controls enough, I manage to bet 200 without the text changing.)
