Playing against Bot and Swindler does not play for me but works for Bot.
You did not provide your game number, so its hard to tell.. but I would assume swindler worked just fine, but you hit cards where there was only 1 choice for the swindled card, like e.g. you hit the only card worth 4 coins. In that case , the game does not let you choose, since there is no choice, but gives the bot that 4 coin card.
