Bug in Simulacrum — mobs not spawning correctly

When I enter the Simulacrum trial, only one area with a chest is available to me. When I start the trial, no monsters remain in the room, but the trial continues anyway. I encounter this bug every single time.

Once, I noticed a monster running around in the next room. It seems the game might be spawning mobs in a different room where I can't reach or kill them.

Please fix this issue — I really want to play the Simulacrum.

same, also dont try to put the simulacrum cluster near abyss, whenever you enter the simulacrum you cant finish it to get to the next wave. it might be because the game thinks there is an abyss inside the simulacrum stopping you from progressing to the next wave.
