Possible AW feature

My is in a casual alliance. We ended up with only 20 players making a defense. Our opponent also has 20 which is not their full alliance either.

I wonder, was this pure chance or did the game limit their side to 20 to match ours?

It’s chance - we’ve been outbalanced the last two (us 25, them 26, us 27, them 25).

Ok thanks. Thought it would be rude to the 21st player if they had tonsit out
