Orehulls stuck on "Looking for food"

The Orehulls in my ranch are permanently stuck in the "Looking for food" state even after they just ate. Reloading the game doesn't seem to fix the issue, or it starts happening immediately after.

The issue happens both with a Fish Feeder, causing one Orehull to occupy it and consume all 200kg of Nori one bite at a time, and also when the Nori is laying on the ground (I've seen a couple Orehulls eat almost half a ton of Nori in a couple seconds).

The main problem is not even the Nori consumption, but the fact that when this happens, most other Orehulls in the ranch never get to see any food and end up dying of starvation after a couple cycles.

Here's an example of an Orehull with over 3400kcal that simultaneously has the "Just Ate", "Ate From Feeder" and "Looking for Food" statuses.
