The curious thing is that if I ask the server for my "guid", he answers correctly. Despite this, (randomly) either clone the nick name (or reply "409" if I set "Unique Username")
Hey morgan1635!
Is this issue happening specifically on your leaderboard(s)? I have tested the demo scene with the demo leaderboard and could not see this issue occur. This could be an issue that is tied to your leaderboard, so if you could reach out to me via email with its public key I could investigate more.
