Further Conversions NPC Bug

[Alandrieas]

http://www.wowhead.com/quest=11525 the quest on the isle of quel'danas is a quest all my characters have been having trouble with.
I spent 1 hour on my warlock today and only got 2 of the eratic sentrys converted.
It gives me things like "out of range" "not in line of sight"
Its really annoying and if you get around to fixing it I would so much appreciate it!!!

Thank you,
Alandrieas

Get as close to the mob as possible, just stand on him first, it is neutral so it won't attack you itself. When you are standing exactly where mob does, then attack it and kill it. After killing it, right click the corpse and use the quest item when loot window is still opened. It should work.
