When doing the quest 'War Games' on Belsavis you receive a bonus mission called 'Neimoidian Rescue' which has you rescue 6 Neimoidians Prisoners. If you're doing this with a group, this can be a pain since you will have to clear groups that you would otherwise not have to, just so you can complete the bonus objective. To rescue a prisoner, you just have to right-click (or whatever interact with npc is bound to) on them and they go free, no dialog or anything. However, if you spam right click / your interact button you receive credit each time you click them. Using this, it is possible to complete the entire bonus mission with one prisoner.
I know this isn't a huge bug and doesn't apply to a lot of people but hopefully someone will find this useful.
Also, this was done on the Republic side. I dunno if the Imperials have a similar quest.
