Steps to reproduce:
Start the game
Observed results:
An incorrect skin is applied and it also sets the name. In this case "Steve" or "Aria". The player name is changed to this and does not get fixed unless you restart the application. Sometimes that works.
Expected results:
The correct skin should be selected and the correct player name should be shown.
Just a player hosted server.
Why is this issue marked as resolved btw?
I can only confirm that it has happened with "Steve" and "Aria". One of the Mods in the comments here claim they got it with "Eze".
