Great work man! I appreciate it, sith defender was giving me troubles.
I'm currently trying to complete the Liberator of Ilum! and going through Ilum quest line to check for missing mobs. Imperial Artillery Droid is definietely bugged.
I found Imperial Mine Captain inside the 2nd phase (entrance: 193,940) of Crystal Ball (1st quest in Ilum story quest line).
Imperial Armsmaster inside the 3rd phase (entrance: -294, 487) of Crystall Ball. I'll report back when I'll find more.
Btw, I tried to copy your Drawing to my Google Drive and add those points I found but it keeps throwing errors at me when I try to edit it. Is there any program you used to create those images? Cheers.
