I don't know when I'll get to this on the cards, but these are definite changes to MY deck cards:
Pickle Barrel - You are limited to 4 food per harvest from the pickle barrel.
Stepchild - If playing in a FotM game, the stable the stepchild lives in must be heated.
Town Hall - It is no longer worth 2 points on its own. It only generates bonus points from Majors (including itself).
The following is a proposed change that will be playtested some more:
Animal Farmer: The animals can no longer take an occupied action space.
