My draconic chest went POOF for no reason

[itsz]

So just now  i was trying to clone my self so i can use etheric sword alot of time, for my reinforced watering can. so i decided to place down a draconic chest where i placed all my item in it include my heart canister, rings, etc after that i decided to goto yusixs' island so i can make more etheric sword.

After couple of minutes trying not to die when making the etheric sword and finished it, i returned to my island just to find out that my draconic chest, shell constructor, shell storage, redstone block just went POOF

I don't know whats causing this it just gone for no reason, theres no where to locate the chest anymore, its long gone
