Tame pacu frys that develop into adult pacus lose the ate from feeder status

and therefore become glum until their kcal value has dropped to below 450kcal which can take up to 2.5 cycles depending on how close to becoming an adult the fry last ate because the glum status reduce their metabolism to 20kcal/cycle consumption.

Update:

Upon further observation the behaviour is inconsistent. Sometimes it does as described above and sometimes it maintains the ate from feeder status as it should (see image below). I have not been able to pinpoint what triggers the bug to happen.
