Ok you were right @chefgaz. Think it needed the update to come back onto account. Cheers!
So by restarting your save you lose all opals you've collected..
@chefgaz ok good to know. Mine aren't in inventory or at the map locations so hopefully this changes. I have little hope though.
I wouldn't advise deleting and restarting like I did as you lose all opals collected. These don't respawn even in new run through as they are tied to your ubisoft account. Really [censored] off I have a broken game.
