I just tried The Crumbling Hall daily quest (after doing it successfully a previous day) and after I clicked the first orb to deactivate a Spirit wall, I went to the orb that wall revealed. One of the mogu behind the wall was evading and said I couldn’t target it. The Spirit wall then came back up and I was stuck there.
Can confirm this is still an issue, the wall came back up as I was wiping out the mogu on the second orb and trapped me.
