1. YNWA,
I have noticed for a while that If you let your partner choose the trump suit you are still able to choose the trumps yourself without your partner having to pass it back to you by pressing A and selecting your trump suit, that should not be possible. I have also noticed that if a bot asks you to select a trump Suit and you have bad cards you can kick the bot and the new bot will select the trump suit, this should not be possible either. This option would only be possible for the table master!
