Lucrehulk core scavenger droid not spawning

Hey. I had this same issue on Xbox. I saved the game at the Lucrehulk Core meditation point and then I closed the game and re-opened. After doing so, I ran passed the Droideka, passed the normal droid with blaster, killed the Raider hiding behind the big thing in the middle. Now every time I ran right, it wouldn't spawn. If you go left towards the big guy with the hammer and then drop down just right of the door you go in and run that way, I was able to get it to spawn running that path.
