Major bug for warlocks, or is it just my character?

[Atheista]

Since yesterday (09.07.2015), while trying to summon Hakkar (which buggs out and can't be summoned or defeated as he despawns), whenever I summon my voidwalker and it has to perform an attack, it simply auto-casts Sacrifice and I'm left all alone and lonely.
Please advise and/or fix this issue as I can't really play my character anymore.

Thank you

Also tried disabling my addons but still the same result.

FIXED IT!
Don't know how exactly, but i did delete my WDB folder contents and copied-deleted-copied back the contents of the WTF folder.

Nothing wrong with Hakkar. The summoners cast something which stops the event. move quickly and quick them when they spawn.

Also, your voidwalker had sacrifice on auto-cast. As soon as you'd get in combat, it would cast sacrifice. Deleting your WTF folders reset it so it wouldn't auto-cast (ie: problem solved).
