Did all on my republic character except: Dromund Kaas, Korriban, Hutta, Taris (imperial), Balmorra (imperial) I can't travel to Kaas/Korriban/Hutta as republic character as far as I know.

I did exactly that to my knowledge I followed dulfy's guide and tracked each planets legacy achievement for droids as I went through them. I finished with imperial taris on a imp character and got the achievement there. Maybe that bugged it out since I did most on the republic character.

I already have the achievement and to my knowledge gone through all area I can with my republic character (Maybourne) I was hoping if cm might be able to tell me if there is way to check if I missed one within the game aside from actually going through them all again. I read that the quest might bug out at times. Best Regards
