Collector trophy won't pop for me after grabbing the relic by the legendary chest and forging the item..
Everything else has worked though, so I'm at 97% trophies..
Edit: Weirdly, I looked through the relics, and you're missing Heimdall's relic (Hilt of Hofud). Which is probably why it's not popping for me. But others said they were able to get it?
