Essence bug

On T7 Lookout map w/

All essence nodes and essence map device craft and
Scarab of: Adversaries X2, Essence Scarab, Essence scarab of calcification, and essence scarab of ascent.

There were two essence's inside of the boss room and once opened were unable to be targeted/hit/damaged or targeted on by totems

Bug reference: 3,551,688,905 and 4,195,908,285

Can confirm. This happens consistently with scarab of calcification for me.
