Metal Marauders don't have a Quest Marker over their heads even though there is an active quest to find/defeat them. I was flying around for a couple of minutes looking for the icon, then i decided to just look for the names and that's how I found them. During the quest Lanterns In Need - there is no orange area indicating the quest objective location. I have not seen any over head marker on an enemy or item that corresponds to this quest. I managed to assist cpt. T'Larto 1/4, but that was during a different quest so I don't know what/how I triggered it. I have not clue how to complete the other 3/4. I have been trying to kill other enemies in different areas but not finding the correct ones. I have tried metal red lanterns, metal yellow lanterns, combined marauders, metal thanagarians, metal marauders, and cultists of the 7 devils - none complete this quest?
