They were hungry, and none of my 6 Shepards bothered feeding them for some reason, and thus
they all fled in a straight line to the edge of the map where they promptly died.
Is this a bug? How can I prevent this?
My entire farming town lost at least 2 weeks of progress with that stunt
Do you have the savefile where this is happening or right before it happens? Feels like the food spawned on the edge of the map 
(Or they performed a bugged depart task. Livestock can die of starvation but they wouldn’t go so far, they would stay in the pasture).
why…what.,.how… why do you have 6 shepards XD? how many animals are we even talking about :’) ?
