Resolved SW summoning circle

[Snoozee]

I am trying to finish my succubus quest, but am unable to. I need to use the heartswood in the basement of the slaughtered lamb. However when I attempt to summon it I receive the error "Requires Stormwind Summoning Circle". During my voidwalker quest it was working fine and there was a purple rune on the floor. Now there is nothing and it doesn't seem to work. Am I missing something or is this bugged?

Abandon quest and redo it if I remember it takes like 5minutes

I was 100% convinced that I was in the right place, after watching a bunch of videos I realised that I was not. My apologies for being a retard.
