Some AI against I played, produce the followin type of error:
“1 91 92” is an invalid action: There aren’t enough pods (0 instead of 1) on hex 91 (and 5 additional errors of the same type)
I wonder why the AI keeps playing instead of being eliminated ?
Imho, because a buggy AI is much better than a dead AI 
It’s too late for such drastic changes. If the organizers chose to allow requesting invalid moves, now it would be a very very negative move to suddenly eliminate such players.
My guess is that it just makes things easier on both parts. And that sort of input doesn’t affect the outcome of the simulation in any way.
