Ritual bug in Channel map

I cant finish a ritual on channel map because stone guards are spawning but not activating.

+1, happened to me twice today. Very annoying.

This can happen on other maps too. Quite often actually.

bump

Has happened to me 2 times. it is caused by those statues, either near a bridge, or at the room with lots of statues. If you open a ritual before killing them all, they become invulnerable in statue form. Ritual will never end.
