I changed my name from legoking225 to dendog_0482 and me and my friend were on a plot that we had gotten far on. I hope there's a way to get it back can anyone help

 

Contact a mod with the light red [Mod] tag or the dark red [Mod] tag to (hopefully) be teleported to your island. They can break any locks you have on your chests. You should make a bed there, and when you sleep in it, you can teleport back to that bed using /homes (yes with an S).
