I wish I could find where I read this, but I have found it to be true.

If you get items for a quest that is not actively in progress, you do not get credit for those items when the quest becomes active and must find them again or have them gifted. However; if you completed a quest before it was in progress, then you DO get credit for the grand item (the prize you get when you combine all of the items.)  So you do not have to combine all of the items again but you still get credit for completing the quest.

Now, if you buy a mystery box and get an item that is part of an active quest, you WILL get credit for that item. If you find an item that is part of an active quest when visiting a friend, you WILL get credit for that item. If a friend gifts you an item that is part of an active quest, you WILL get credit for that item. It is only when you get an item for a quest that is not actively in progress that you do not get credit for it.

However, you can still use that  item to complete the collection and get the grand item/prize along with the rewards. I think that is the main reason to buy the mystery chests, so you can complete collections for the rewards. If all we had to do to finish a quest was visit friends and guy mystery chests, this wouldn't be much of a game because you wouldn't have many quests you had to actively participate in.
