I was just replaying this game and it glitched out on me, the first time I've ever had it happen.
Jester was at +1 weight, I was at +5 Weight. A joker came up as the reverso-weight. I lost my weight down to +1, and the Jester gained up to +5. However, it went back to ME and I was back at +5 and I think I gained up to +6. Camera went back to the Jester view, and the game stopped responding to commands. I couldn't hit ESC or anything, I had to close the game down.
I had 3 draw-hands, I think the Jester had one too. We had the Joker card come up two other times in previous turns. First one I think was Jester > Player, and then the next one was Jester & Player +1. This was the third Joker cane up.
