On behalf of player _ItzGonzo , I would like to post that this player does not have a mineverse account and changed their name and they would like to have their plot name changed and chests unlocked and/or relocked with their changed name, Gonzo309 to _ItzGonzo_ @ZeldaNinja
This is a bug that cannot be fixed at this current stage, the only way you will be fixed is if you or this person changes their name back to his or her first name. Resolved.
