Mirage generated has no chains

Hello,

Entered a mirage with the Afarud supposed to spawn after breaking the chains.

The area is so small, the chains that i'm supposed to free are not even there. I cleared it all and even after exiting the mirage, the djinn is still impaled. Meaning that i did not free the chains.

And since i was supposed to get a Black Barya, i am quite disapointed to miss out on garenteed divines.
