We need to know more about what you are talking about.

If you mean Treasury Chests as from the Kings Quests, there are only 16 of them in that Haven Castle treasure room.

If you mean the Share the Wealth treasure chest. If it's repeatable for you then you have to know that it might not actually happen for days or weeks, or could happen sooner. Like the Giant, those 'random' quests 'can' happen once they become repeatable, but they will when they feel like it. You can push the process along by walking through a gate hundreds of times, or whacking with thousands of Energy.

If you mean those Museum Treasure Maps. NO, please NO. There are no more of them if you have done them all. There are some repeatable, and some you can get in the Scientists Castle too. But those Treasure Maps S.U.C.K. I won't tell you what those letters stand foor, LOL.
But if you like that C.R.A.P., again these letters stand for something too, then be warned that the St Patricks holiday Event had about a dozen of those that you had to complete to complete the whole Event.

I didn't mind the museum maps so much, as a change of pace. Doing them wasn't all that fun, but seeing my items show up in the museum was neat. Reminded me of catching bugs and fish and fossils for the museum in Animal Crossing.

Still, I can see how doing a ton of them in a row for an event would be irritating.

That's still no help to those of use who are trying to help you.
There are over 400 different quests in this game.
Which one is giving you trouble? In particular, what kind of trouble is it giving you?
Most quests are of two different kinds, whack bushes or beasts till something appears, this can take a little or a lot of Energy. Or walk around in different squares until something appears, this can take almost no Energy at all but it can take time.

and you need to find 10 clues

I vaguely remember that one..the chest was somewhat buried in the ground. Theana, if you click on your map icon, when the page opens, check mark the "active quests" area..which is at the bottom left. Top left will give you the name of the active quests you are doing

It sounds a lot like one of the museum treasure quests, they all follow a format similar to that. You find a bunch of clues whacking bushes, a mound of dirt with an x on it appears, you dig it up, get a key, open the gate, whack more bushes for more clues, etc.
