I have a bit of a quandary, I am trying to complete my Health Food Collection and one item is the Mirabilis Fruit which I have five of; the problem lies in that when I click on the tile for that fruit or even 'Quick Fill' it says I have none even though it is clearly in my inventory. Am I doing something wrong?

Fine then, let me rephrase this..
In order for an item to be recognized when completing certain collections like Health Food, does the item only count if it has been bought from a NPC Shop?

On second thought..forget it. I may have accidentally stumbled on the answer.
Thanks.

Hi! It doesn't matter where you obtained the item from. Just make sure the item is actually in your inventory and not in your item gallery/food pen/storage etc.
