Well the "workaround" worked. (not really a workaround when it involves completely starting over) and now whenever I go to a location where there should be an opal, there's just nothing there. I'm trying to update to 1.02 now, but honestly if that isn't fixed I'm probably just giving up. Not like anyone from Ubisoft will read this.

Okay, going back online made it so I could LOOT opals, but when I go into the my inventory it shows 0. What a mess.

I'm having treasure hoard issues as well on PS4. The Oxenfordschire Hoard Map stayed in my inventory even after I looted the hoard itself (and I got the reward properly), but the Suthsexe Hoard and Sciropeschire Caustow Castle Hoard both don't give me a reward when I loot them besides XP, so I reverted my saves to before looting them as I figure it's more likely to get fixed than it is to get fixed and give out the reward retroactively.

Yup, also got this bug. After restarting on version 1.00 like a lot of people are suggesting, I've noticed that when landing at your town you get the "seer solace" quest pretty much immediately, while on my 1.02 save, the reason why I couldn't talk to her is because the quest never actually showed up in my log.
