I was killing Lord Grathan's droids for their power cells for this quest yesterday for about 20-25 minutes and cleared the entire radius where they're found about 4-5 times over and not a single power cell dropped. I had a lvl 50 grouped with me to help speed questing along and thought that, for whatever reason, this may have something to do with it. So we ungrouped and I continued about killing more droids, sometimes by myself, sometimes i'd tag the mobs first, hit em for a bit, then the 50 would finish em off. No power cells.
I was still getting credit for the kills as they would drop regular garbage loot, credits, etc. but no quest items. I even reset the quest and started over but to no avail.
Don't suppose anyone else has had this problem or know of any reason why the class quest items wouldn't be dropping.
thanks
