Wretched Defiler spectres and their bone summons

Can you please fix their AI? It's literally unplayable in any closed spaces, whole screen is filled with their bone summons and it's impossible to see any boss attacks. Sometimes they spawn so much summons that it causes huge fps drops and crashes (in simulacrums especially due to the length of fights).

And also this. Any died bone summon also leaves a corpse, that won't disappear in any time, unless you consume these corspes for other skills like offerings.

Couldn't see a single maven skill due to these corpses and wandering bones. Memory game is barely visible.
I hope that's enough of evidence that their AI endlessly summoning bones is an issue.

Same issue. Can't see anything when fighting Maven as well as Eater of World. Better to have an option in settings to toggle show corpses.
I think it's been asked before this issue for people to get better fps.
