Today's patch introduced two new bugs to the nightmare fractal. Firstly, the altars between MAMA and Siax no longer display capture progress bars. Secondly, /gg-ing during Siax no longer properly resets the encounter. He remains hostile rather than despawing and being replaced with the interactable orb that used to restart the encounter. Respawning places you inside the arena and in combat immediately and notably makes the Mistlock Singularity inaccessible.
