Some rituals are impossible to start

Map: Abyss
area effects: Chilled ground, enfeeble (maybe this affects)

Can't press the ritual to start it, some rituals require to kill monsters to be able to start it, however cant start this one even though I killed all enemies. Possibly an enemy spawned inside the wall making it impossible to kill him

Overall monsters that require you to walk over their spawn points for them to spawn seems quite buggy in some maps(abyss, creek from my experience). Their spawn trigger areas should be adjusted or made bigger, as I do believe in this instance the bug occurred because monsters spawn point is most likely inside the wall in top left area of the picture
