Unable to see any players nor npcs

I have a weird phasing bug on one of my chars. I cant see players, NPCs nor objects (such as mailboxes, fires) in Orgrimmar and Durotar. I have seen few ppl with the same issue and I am only able to see them, and they say the same. I have tried deleting cache and dying, teleporting away and back, summoning - nothing helped. Ive also opened a ticket ingame, but the issue hasnt been fixed even tho it was said to be taken care of by a gm.

Has any1 ever had that bug? Any ideas how to fix it?

a gm should be able to solve the problem but meanwhile you can try to solve by dying for falling damage

I've had the same experience with the game whenever I'd get in the game, IF I manage to get in the game... I get disconnected from the server most often though
