Rancher keeps calling the hatchs at the grooming station and they won't go to be groomed even though they are glum.
The rancher stays there and the hatches never go. She stays until she has to go to the bathroom, or until she can't breath anymore, or until the schedule indicates her to go to sleep or other task. But the critter never goes there. If I deconstruct and build the station again it fixes for some times, but the bug repeats after a few cycles.
Build a hatch farm, and wait.
