It seems to be working on my end, and others have mentioned getting the True ending which wouldn't be possible if you couldn't feed her on Night 1.
Are you sure you got all of them? There are 8 ingredients total for for that level.
Yeah, i was getting either 6 or 7 ingredients there, so now i'm sure i skipped something But i also never chose selling point that would give me ingredients, i always aimed for either speed or max health. Now i know that i need to try again and aim for "true" ending, instead of magic pixie ending. Thank you
