Wow, that was a very weird ruling. I see that it only applies to Ball. It would be so much better if Ball said to turn your -$1 token over (which is how we play it) or to put it somewhere, instead of "taking" it.
First I thought it meant not having a -$1 token again, ever, in this game. But I see that it only means losing it right now and then you can get it back later.
So it means that your token can affect me? Your -$1 token will have the same effect on me as my own -$1 token? So I can actually have two -$1 tokens? And the next time I get $, I can choose which one to lose first? Even the idea that another player's token can work for me, is pretty counter-intuitive to the rules for the tokens.
I really wish that Ball would get a fix like Pirate Ship about this, just to avoid a ton of confusion and strangeness.
