Mission Quest Help

Some of my mission area map icons (ie: Fort Ranik, Nolani Academy) have one sword through them and some have two.

I am assuming that the single sword map icons implies that i missed a bonus part of the quest.

If my assumption is correct, can I go back and get the nice xp from the bonus quest?

Also, will I be prompted about the bonus or do I need to join someone who has not completed that mission?

I do not want to wander aimlessly since it seems I do not always get the green arrow on missions as in the side quests.

Any help is greatly appreciated.

You can always go back and redo any mission. You won't get the experience for completing the mission more than once, however in your case you can get the bonus EXP. Do a quick searh for bonus missions so that you know which ones your looking for because NO there is no little green arrow.

Thanks a bunch Auntie!!
