Yeah, we tried running a sow out of stamina. From the swamp in the N.E to the south eastern tip of the island, never stopped running once.
I will just work around this like I do with the broken buildings. GM spawn in animal deeds. I know they won't breed but, I can just spawn another in when needed.
It doesn't make the game fun but, at least it will be playable without constant frustration. I am already recovering from a stroke, don't need another
