Temple

I can't progress in my temple past a Hall of War room because the mobs neither take nor receive damage so I can't move to my Architect room.

Yup, same! I have a companion/minion build.

Same. Bug Report ID: #4223974441

note: going to character select and coming back gave a brief window of being able to damage them

I am trying to run it and hit a spy room, the room would not let me deal any damage to an monsters, i needed to respawn at nearest check point, then kill them at the door of a former room. Ran to a Vaal room and it is the same thing.

The temple has it where only specific stuff can deal damage, and only some times.

Then after that, it bugs out my spirit skills and i need to click on them then repeatedly right click to reactivate.

I'm getting the same issue, can't progress because "bloodrite" enemies won't take any damage in a Locus of Corruption room.

I was able to lure them all out of the room to kill them outside it, but then the room was bugged and I wasn't able to complete it.

Temple same issue, bug report reference 665596437

same i play with granede vaal guards and i seem to do damage with unearth but my mionions just do lighten up the room.

Same for me. Companion build and managed to progress through 3 unkillable rooms with kiting/checkpointing. Now im 7/8 rooms and cant progress the last one.

Same here, happens mainly at spymaster and commander rooms, mobs are not targetable nor get any damage, have to pull them out of the room to complete it. very annoying...

Same issue for me - multiple rooms - it seems to be Vaal enemies.
