Missing mobs/peeps and mailboxes

Hello hello!
I have a small problem right now. i cant see any mobs/questgivers in Shadowmoon Vally. not even a Mailbox.
and the mailbox problem is following me through the world.

any tips?

Any change? Has it been fixed ?

Made a post about this also a few days ago, and i have seen several that did too. still nothing has been done.
I tried to make another post about it about an hour ago and now they have deleted it.
This is both annoying and abit slacky when many people have posted about this issue over the past few days.
