v0.9.4 here
I’ve been playing about 70h on this town and had horses for a while. My town was attacked by raiders after which I decided to move the stables closer to the city. As it took them forever due to wood shortages, my whole herd had died due to starvation and I bought three new ones from the merchants.
Yesterday everything was fine. Today I loaded up my game and saw that the three horses are not assigned to their stable anymore and just standing idle next to it.
