Ritual at 2/4 but cannot activate rest 2

Seems very much like a bug,
Finished the map, can find the remaining 2 ritual, but no way to activate it, just sitting there

This happened again, I'd say every 5 map this happened
And I gotta say goodbye to the key because of bug
Tried switch lanugage/region, non works

Same for me. 2/4 rituals on Hidden Grotto. Last two cannot be interacted with.

Just did Crypt map, 1 of 3 were unable to be activated.

Just lost an audience wit the king because of this. GGG please reimburse

Yeah same here. I have a ritual that can't be activated even though there are 0 monsters left in the map.
The other day i also had a ritual that i could activate but could not finish. There were no monsters left to kill but the ritual wouldn't stop.

Yeah happens quite a lot i'll say once every 3-4 maps, i can do the first 2 rituals but the game doesnt let me activate it to start the third and fourth ritual. T.T

Same issue on Hidden Grotto 2/4
