So i finally gave up on Blizz doing anything about my ticket or my missing quest on my locked 48, went and leveled to 49.
I was unable to level in durotar like i had been able to earlier, everything was current-timeline level and i was unable to talk to chromie to even figure out what timeline i MIGHT have been "stuck" in at 48 (forgot what I was in hitting 48).
Went to BFA cuz I'm pretty sure that was my literal only option other than groupfinder dungeon/PvP, and leveled from 48-49 by opening treasure chests (like 6-7K xp at 48, same as an entire quest) and doing a couple quests.
Soon as i hit 49 my missing quest in Oribos appeared on my Oribos map (checked from Drustvar). Shocker. Level gated.
F U blizz. Keep surprising no one.
