So last night I was going through finishing up things so I could defeat the final boss and platinum in one go.

I noticed I was missing some skins and checked online to see which ones I was missing. I go and defeat the last Legendary beast, which I thought I had already beaten, and I collect the last skin and the trophy didn't pop up. I have all 16 skins and confirmed I wasn't missing any. I restarted my ps4, deleted the game and reinstalled and even went back to a previous save before killing the beast to see if I could trigger the trophy. Nada.

I've collected everything else in the game except for a helmet and armor swatch that gltiched and didn't pop up after I finished the side quests. I've even completed and obtained all other trophies.

Anyone have similar issue? I'm playing on the ps4. I love the game, I just don't want to play a new game just to collect some skins. Sigh.
