So far in my time in Minecraft I've had three different usernames. My first username includes my real life first name because I made it when I was like 8 so I wasn't very smart. I used my last two usernames while playing Wynncraft which makes my current problem very confusing. When I put my mouse cursor mine or other players' usernames in chat it shows one of their previous usernames if they have one. My problem is that it shows my previous username as the first one I used which I didn't even play Wynncraft with. This shows my irl first name which I don't like being shown. If a way is made that allows me to completely hide or change this then I would feel a lot more comfortable talking to players in chat.
