Detonate Dead Unusable in Rituals

Detonate dead has difficulty targetting corpses, when surrounded; sometimes this is an issue during breach and simu but especially so for rituals. I've tested many rituals and I'm unable to detonate dead even when I have clear LOS of the corpse.

I understand LOS is important as detonating dead behind doors and walls may be too OP. However, swarms, not even counting being body blocked by my own minions, should not block detonate dead's casting.

Yeah, that's really annoying.

I hope they make a "fail-safe zone".
It should be a thing that you can detonate corpses close to your feet no matter the "line of sight".
Standing next to a corpse but being unable to detonate it is horrible and with a small "true sight" area around the character the "I stand behind a wall and cast behind it" wouldn't be abusable.
