After entering the Fetid Masoleum, there was an NPC that triggers an event to kill 5 waves of enemies to keep them alive in front of a locked door. On wave 3, an enemy spawned behind a locked door (need 2 bloodstones to unlock) so it was “unbeatable” at that time. After getting the 2 blood stones and opening the door, the enemy was killable and I “lost” the event because I killed the last enemy “too late.” Please fix enemies spawning behind locked doors.
