Shadow Missions

There is a bullet point that says: "You will receive one or the other quest, not both at the same time. You may receive the other after completing, failing, or giving up the given quest."

However, that's not true. There are instances when a player will log and receive both quests at the same exact time. I don't know if there's a result that happens all the time, but usually, a player has to complete both or the quests expire. I was actually trying to find out if it's possible one can receive the quests again if he/she lets both expire, but...

Need someone to clarify.

If you log on or change channels while inside before receiving a quest, you can get both at the same time. IF I remember correctly, letting both expire is safe, so you could cancel both to ensure yourself enough time for each.
