Forza Horizon 3 - Relic Hunter broken

Check your achievement history and see if you maybe collected it without realizing, as this achievement should trigger when you've completed 15 barn finds, not when you reach 100%.  I'm also stuck below 100%- I think there were some limited-time event-related barn finds that I didn't collect.  But I do have the "Relic Hunter" achievement  anyway as I've collected at least 15.

no. 19 Barnfinds and stuck at 86%, although in the meantime i found the barn find on Blizzard mountain. still 86%.

Strange!  Are there any other achievements for other games that aren't unlocking, or just this one?

I'd also recommend you take a look at the steps in this guide and see if that might help: https://forums.xbox.com/en-US/thread/88E985A3-4139-430C-9400-93771D0C1004

Best of luck!

Just this one isnt unlocking. Tried everything from the guide already.

Finally unlocked it.

Disconnect Xbox live.

Delete Save File from Xbox.

Start new game until you got your missing barn finds and restore them. (Hopefully get lucky unlike me and get cheap cars to restore, otherwise it will last longer).

Keep Game open and go in Settings - delete save file again.

Reconnect Xbox Live.

Go back to FH3 and it popped.

Really Microsoft.....never got an answer for my Reply. I used Chat Support, Email, Forum and you ignored me completely. And i had to use strange disconnect/connect Solutions to repair your faults.
