Sietch/Instance Hopping for Blueprints

This has probably been said before but I am going to say it again since I just figured it out myself. Constellation chest respawn timers are unique to the sietch or DD instance. If you need that special blueprint that only drops from certain chests and you are waiting on the respawn timer just hop on over to the next sietch or DD instance and try again. I just got my last chosen armor piece by hopping through 8 sietches. I am now looking for a jolt sword by hopping through the 3 DD instances on Harmony, but no lick yet. And speaking of Harmony it is great seeing people everywhere again.
