Dragon's Bane Trophy Glitch

I know I am not alone in this, there are message boards all over the place with people having this problem.  Some resolve it by reloading to an earlier save and fighting the last dragon again but I have not had any luck doing so.

Just keeping this alive, hoping to get an answer.

I did a completionist run as well and finished the story but the trophy still hasn't popped for me. Can't do anymore quest because I finished them all for the one playthrough. Any other way to work around it?

So glad I did a save before I started my last Dragon in the Hissing Wastes.  I exited the game, turned off my xbox one. Turned on signed in, made sure I was signed into EA games, reloaded the save, made sure I had the High Dragons, Dragon Hunter set as an active quest  it's in the Journal under Collections, ( I did'nt in the previous attempt), and the achievement poped.  I don't know if all these steps were necessary but anyway it worked thankfully.  As a completionist it was pretty annoying. but I'm smiling now 🙂  Hope this helps someone.

Gah I did the last dragon, last night and it didn't pop, 105Hours in and I don't think I have a backup save as I went off to do some story after, I think the 10 Agent one has also bugged on me as I've gone through the Perks and I have 11/12 Agents and it's still not popped either... I hope they patch this, as my next run will be on Nightmare and I'm alittle timid on taking on the Dragons on that difficulty

Definitely not loving this. My meter reads 10/10 and my earliest save I think I have is just before I go to beat the final boss. I hope they fix this because it will definitely affect my future decisions to invest time and effort into a game I can't complete.

I am also have a similar issue. I defeated all 10 dragons and my completion meter recorded 8 out of 10, after reading some workarounds online I decided to load on older save and defeat the last 2 dragons after doing that my completion meter now reads 4 out of 10. Could you please fix this as I have every other trophy.

I'm having the same exact problem. I played through the whole game, attempting to do it as a "completionist." By the time I killed the final three dragons in Emprise du Lion, I realized it hadn't given me the achievement. I didn't auto-save because I expected the game to work out and I thought "9/10 dragons, hmmm... maybe it is trying to count the archdemon as one of the dragons."

Today, I decided to complete the game, which I played on nightmare mode. After completing the game, I looked back and my ratio had actually dropped to 8/10. In the game, it says I have killed 10 out of 10. On my achievement list, it shows I have 8/10. I'm not willing to replay the whole game just for this achievement, but I would appreciate it if I had some help resolving this issue.

don't get your hopes up EA will not answer I have post up about this for the xbox 360 I have tried the load up a save before last dragon and it still won't pop if EA can't be bother to fix the achievements then DON'T realease the game with achievements.
