If you don't want your treasure stolen plan the burying better. Last step takes 24hrs so dig it up and bury it again if you need to so you'll know you're able to dig it up as soon as it reaches 5 stars. I leave some of my 5 star treasures buried for others to steal because I have plenty of silver, but not many friend captains are stealing. Why not?! It's part of the fun!! Shame there's no in-game message board or something.
