Multiple Marauders in One Fight

Hello, I’m Clublightt, I logged onto Origin Realms today and entered a spire. When I entered, I immediately heard Marauder sounds and wondered what was going on. I rotated myself a bit so I could see through the doors and saw two active marauders (on the second stage) right next to the door. When I entered, the second marauder disappeared and reset for the fight, and the first one stayed.
