Harandar Glyph Hunter BUGGED! FIX PLEASE!?

I’ve been trying to complete Harandar Glyph Hunter for over a week now, and it just won’t trigger. I have flown through ALL the glyphs in Harandar, but the ones at Nordrassil and Shaladrassil will not get ‘checked off’. I’ve tried flying through them with my other character, relogging, reinstalling, whatever, nothing works. The glyphs are grey, indicating that I’ve flown through them/discovered them, but the achievement just will not complete. I’ve made an in-game ticket, but support just brushed me off. At this point I’d rather you sort of ‘roll back’ my character to a pre-glyph state so I can at least try to collect them all again or whatever.

Please fix this, I want my Midnight Glyph Hunter achievement!

“The best way to confirm if something’s broken, is to check it out yourself”

So I went across Harandar on my toon that didn’t yet have the Glyph Hunter achievement itself and also across these 2 specific spots and I received credit for all Glyphs in one fly-through.

They don’t award achievements or handle bug reports no.

If you experience a bug ingame, at the EU side we report bugs through the ingame bug reporter. Maybe riding through them without skyriding at a gentle pace will work?

Except it’s not broken for everyone, so that’s a weird response. It still is broken for me. I’ve already tried everything I could think of, so no, ‘just gently flying through it with steady flying’ doesn’t work. Very helpful post, except it’s not.
I’ve already submitted a bug report about this, and again, and again, but apparently it’s not important enough for them to either acknowledge or respond.
