I originally posted this in the customer service forum and a representative told me to post here, so here it is:
I went to complete the mission "A Lead" on Dromund Kaas and as soon as I click on the crate, I get the quest completion window. So I turn around to head for the spaceport and notice there's a timer on my screen. Apparently, there was a "bonus quest" to follow a droid to get the item I needed to complete the main event quest. Well since I had no idea where the droid was, I abandoned the quest to try to restart it. However, since it was a BONUS quest and the main quest auto-completed from me clicking on the box, there was no way for me to get that part of the quest back. I tried resetting the Grand Acquisition quest, but that did nothing. So all that running around and standing in line and waiting for others to complete the beginning parts of the quest were for nothing.
What were the devs thinking? Put a necessary item on a bonus quest? One that can't be retried because the main quest that it comes from is completed before the bonus starts? Terrible, terrible implementation. I am sorely disappointed.
