I was doing a quest (Specifically Saggitarius if that helps) and one of the items I needed to get was shown in my shop on the shop search, so I pressed the "Move" button, but then when I went to complete the quest, it said I didn't have that item, and when I looked in my inventory, it wasn't there. Why did it just disappear? Also, the item was Marshmallow Cuddlefish Plushie if that also helps. I had to buy one to complete the quest.
