Skyscale Rider: Tarnished Coast Bug

Hello there, i've got an issue with the Achievement Skyscale RIder on the Tarnished Coast, where one of the Reality Rift doesn't give me the completation of this achi, in particular is the one at Irwin Isle Waypoint, in Mount Maelstrom area, i try to do it with 4 different characters, i try to wait the daily reset and also i try to unistall and re install the game, but nothing change at all,anyone had my same problem? anyone know hot to i can progress to this?

I am also having the same problem :(

Same problem

I'm stuck on completing the rift west of Althoma WP in Sandswept Isles, so I feel your pain.

I am having a similar problem, but believe the issue to be one of the rifts in Metrica.. has anyone had any luck getting this resolved?

I completed the Tarnished Coast rider achievement earlier tonight. I did notice that the behavior of some of the rifts is really buggy. Still need one in Sandswept to complete Season 4 rider and finish the main achievement for good.

Actually... the S4 rift that I needed wasn't in Sandswept at all. Apparently the rift required for Vision in Domain of Istan was the culprit. I'd gotten enough to get credit for it for the Istan Vision quest but not enough for it to count to the S4 Rider achievement. I now have Ruler of the Skies completed!
