Playing Carcassone seriously means reading the instructions for how farms work.
What I find hilarious is how every expansion has some kneitch that seems to totally contradict how the rules work. L’moshol, in one expansion it comes with special meeples in every color plus gray, which isn’t one of the playable colors. There are at least two expansions that have changes to the farm rules, but the original rules mentioned are different than what’s in the original box.
