Ya’ll are gonna have to wait for Krieghund. I don’t see that intentional over-purchase is disallowed.
Re-reading Krieghund’s reponse, he says “if for some reason you have purchased more units”
STILL room for interpretation! Can you over-buy intentionally, or NOT?!
I’m guessing intentional over-buy is not allowed, and that if you were playing face to face, you could stop your opponent during the purchase phase, but what do I know? No rule against intentionally over-buying, and Krieghund hasn’t yet said there is.
