Final collection conjuration

[fluid echo]

Can anyone help me out? I finally got the game and I am one conjuration away from 100% completion. All of my collection chests in the highlands
Are done. All of my collection chests in hogsmeade are done. Hogwarts done. I’ve checked and rechecked all 12 vivarium chests. I checked a map of all the butterfly locations and I can’t find any more. It’s driving me nuts. PS5 btw
