My dupe is currently calling the smooth hatch that is standing in front of the station to be groomed, but the critter won't hop on. The critter just stands there with the tag "being groomed." This is leaving my dupe in a bugged state of constantly calling.
This seems to only be happening with my smooth hatches. The others seem fine.
I managed to circumvent the bug by manually making the dupe to walk away, then wrangling the smooth hatch that was stuck.
I followed the build format for a simple hatchling farm from this link: Hatch Farm
I then developed my own design with two conveyor loaders, a critter counter, and an alert module that tells me when the critter count is under 8.
I filled the left side with 8 smooth hatches, and eventually, one got bugged in front of the grooming station.
The grooming station is on priority 8.
