Simulacrum Wave 20 1 Monster remains spawned in wall, not despawning

Reference number 3,027,593,523.

My cursor is roughly on the bottom half of the column beneath the lamp, or the furthest right circle in the overlaid minimap. The stuck monster cannot be interacted with either by attacking, taunting, ancestral warchief attacks or leap slam.

Did swap characters to finish the wave, and did have a Kosis spawn.

Same to me, only i dont find the bugged mob.
