I found a workaround to obtain those bugged achievements. TLTR ; re-do them on a new character on the same server region.
The root cause is a disconnect between the server and the region. On the right side you see the achievements you completed on the server. On the left side, the counting and totals with some missing(does not add up) on the region.
If you create a new character within the same server region, you will see which achievements are ‘really/region’ completed. You will need to re-complete the missing achievements on the new character.
In my case, it was visiting WF and completing tempest (I bought a shard run).
Expansion is amazing so far! You guys fixed some of the achievements in this list (first one that comes to mind is the Hamlets & Outposts achievements). I’ll put together a list summarizing the remaining issues in a few days probably once I play more and try to collect all the lore pages.
Its pass a year already, this supposed to be fixed on a day 1 of live, but everything what you will get, another community manager will come and will say the same as all this year “ we will fix it! No worries, give us 3 years more”
After downloading today’s patch and testing out loading into the game and opening the achievements menu as fast as possible, twice, I have NOT gotten an “Uninitialized” bug! I don’t know if it’s fixed for good, but replicating those steps previously almost always gave me the “Uninitialized” screen shown above.
