So for those that don't know, there's a new theory in regards to treasure chests in this game. Supposedly chests do not respawn but what happens is that whenever you rank up, not clear if it's world level or just per Adventure Rank, new chests spawn. There is some weight to this because I've seen a chest yesterday right next to a puzzle I previously cleared that also required me to kill enemies before I could open it. There's no way I'd miss that chest since it's so blatantly obvious it's there. So this basically means, don't bother doing chests routes or looking for respawned chests. If you see a new chest, you either missed it completely or it's an actual new chest that spawned.
