Guild Wars 2

For some reason, the last dragon scale (the one nearest to HotW entrance, the one under water) won’t activate for me and the achievement is stuck at 90%.
When I try to press F to any other scale I already activated, my character plays the “no no” animation of some kind indicating there’s nothing to do here. Pressing “F” at the final one doesn’t do anything, however.

Steps I tried:

- Swim around the scale and try from all angles for no result.
- Run to all scales again and press “F” just to make sure it’s not one of them.
- Guest to another server and try there, no dice.

I did report this, does anyone else have this problem with any of the Hunt the Dragon achievements?

You’re not alone. There’s a thread in the Bugs section of the forum about this issue: https://forum-en.gw2archive.eu/forum/support/bugs/Hunt-the-Dragon-Scales/first#post2895964
