voidwalker sacrifices itself when told to attack(bug)

[audron311]

ok so this has been an ongoing problem since i hit 60. when i tell my void walker to attack, for the first second it moves and sounds as it would if was gonna attack something. then suddenly it stops and sacrifices itself and now i have a bubble.
All other abilites work correctly. I tried moving thier posistions, manual clicking, reseting all key bindings to default, turning off ALL addons. nonthing i can think of myself will fix this. plz help this pet is completly broken as it is now.

Try deleting your WDB folder.

Greetings,
Same problem here, and it seems that deleting WTF or/and WTB is not working.
Any solution for that issue ?
Thanks for reading
