Bug Report ID: #2052901220

As title. There are 0 enemies remaining in the map. I can't interact with two out of three ritual altars. The one altar is clickable and shows rewards, but I am unable to interact with the other 2 in any way. Ritual counter shows 1/3

Sluice map if that makes a difference

Same here, 1/3. 0 monsters remaining. Hidden Grotto map.
