Before you move this to Bug Reports like the other post regarding the same issue, can you acknowledge there is an issue and a fix being made?
These three achievements have been
BROKEN on XBOX since
November 2019. Meaning
NOT A SINGLE PERSON has unlocked them since they have been broken.
This means on all of Xbox...
IN THE WORLD.
Last recorded achievement unlocks were
Savior of Elsweyr - 03 Nov 19 at 4:52 pm'
Wrothgar Adventurer - 20 Sep 19 at 10:36 pm
Big Score - 04 Nov 19 at 10:20 pm
I for one have cancelled my ESO plus for the last six months and refuse to buy another dlc/renew until these are fixed. This was my favorite game and I sunk 1000 hours into it. The lack of support on Xbox is astonishing. Its literally been almost a year to fix a core function of the game.
What is the point of sinking so much time into a game that won't reward you correctly. It takes tons of time to do Wrothgar and Elsweyr... every quest... just to get nothing out of it. Now those people are left with dozens of hours, minimum, with nothing to show for it. Nobody from ZOS even ackowledges it. Xbox achievement hunters are getting the short end of the stick.
