[1.1.1] Win 7 - Realm Cannot be Completed

I’m in Perdition’s zone (Sanctum Umbra) and I have the “cleanse 3 obelisks” objective, and while 3 obelisks SPAWNED, only 2/3 of them were cleanse fights, the other one just gave Favor and did not advance the counter. So now I’m stuck in a map with an inactive exit stone, the Candle, and the Perdition statue: I have checked every single corner and destroyed every interactable. Only option was to save+exit and redo the level.
