Yep. That is a good point and it happened to me with a different game. I remember in our group when we were playing the old Decipher Star Wars CCG. Someone said it worked like so and had convinced someone else and hence the rest of the group (five or so of us.) I argued that that made no sense for it to work like that. That they were wrong. Pointed it out in the rulebook (I always read the rulebook even if it isn’t my game,) explained why it working like that would be terrible game design, but was overruled.
So we play for about a month like this until someone else comes in and points out that I was in fact correct. “Did I not sit in that chair and say exactly the same thing?” I think they didn’t really care which way was right so much as that I be wrong.
I’m still waiting on my apologies but considering how when played correctly I started crushing everyone I’m not surprised they weren’t forthcoming.
The OP is lucky with his newfound knowledge though. He got new A&A games this week.
