Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi.
I have this loot bug in AV , very annoying. I almost never get to loot enemy corpses . I get the channeling bar but not the loot . Plus if i loot NPCS after 2 or 3 i get buged and get stuck in the loot position and the loot icon becomes gray for all the corpses.
i tried deleting wdb , no result .
i have to restart the game and it goes away . but i loot a body and its back.
anyone else had this problem and can i get some help?
i see other ppl looting with no problems .
i need to loot enemy corpses especialy for rep turn in .
TY

ok this is frustrating . so much.
i killed an ally rogue with no one around and still could not loot the corpse.
