Hello my rancher has been occasionally at starving status even though she has access to food. The only thing I prevented her from having access to is the outside (the ranch) where there are germs outside. The reason being that her immunity was a bit low. The first time I solved this I allowed her to briefly have access to the ranch again, as she was just standing still in the starving dupe stance. She also failed to move even to use the restroom (which she also had access to). The only door I used to prevent access is the one to the immediate right of the chlorine wash basin in the rest room.
I provided a screen shot and checked her navigation access to the fridge. All checked ok.. This is the only dupe in my colony that this is happening with.
Create rancher? dupe and play normally (prevent access to non food related areas of the base, I think. I'm not sure exactly what is causing it).
