How long do I have to complete an XPedition? What happens if I don’t complete it before time runs out?

some xpeditions have a time limit if time runs out before you complete the quest, it’ll move to the archive/completed quest list as missed unfortunately, you will not be able to finish an incomplete quest that has expired if you have outstanding rewards to claim, you will still be able to claim them, but you won’t be able to earn additional rewards from that quest
