I'm assuming it's either token dump or reset required at the end of BB. I believe with mine set to on, I get neither. I don't think it changes the play at all.

My Shaman has eaten more than it gives up the whole time I've owned it. I believe it is because I haven't learned how to "read" the signals it's giving, or at least not how to react to what I see.

Even when I know the tricks, machines still go cold once in a while.
