Quel'Delar sword, Hall of reflection quest BUG

Hi warmane´s masters

3 days ago i got the quest in the AH for 2,5 gold to begin the quest to get that sword with my pally Nayocrow... i did it all good, i did all the quest line till Hall of deception, then it says to kill the Quel'Delar and loot him, it did let me kill the sword but didnt let me loot, i tried resetting the instance many times and killing that sword again and doesnt let me loot, then i tried abandoning the quest and getting it again, and the same thing, just doesnt let me loot it, dont know if that got bugged just today or what, cause i have seen many people doing that quest everyday and finally they get it, but in my case doesnt let me

any help please?

thanks a lot for your comprehension, ill be here for if u warmanes master can help me or if it did really just got bugged dont know what else to do,

have a nice day!
