It was pointed out to me that somehow the "zombie's can't run" rule ended up accidentally cut from the Bloated, the Stevedores, and the Corpse Cart. That has been mended [though it throws off the page count].
Separately, a suggestion that the toughness of the Jolly Boat [Corpse Cart] be reduced by one makes sense. The T8 was taken directly from the wagons rules [as was the cost, etc], but wounding T8 requires a Strength of 5 or higher, which is difficult to reach early game, making it potentially invulnerable; on the other hand T7 can be wounded by S4, which is easily attainable through weapons, even in the first game.
