Two yaml files with the same name but different UUIDs stops private messages

We recently had a player unable to receive private messages. After debugging the code flow it was due to 2 yaml files with the same username but different UUIDs, after deleting these and rebooting the server it resolved the issue.

This happened we believe because the player created a new account with a different name, renamed the original account to a different username, then after 30 days renamed the new account to the old account name, this then caused 2 yaml files with different UUIDs but with the same name.

Interesting. I can see how that could happen. Might not fix it right away, but it's good to keep in mind if someone else runs into the same issue!
