As niki says we have not added any other skins. However after issue's with xp saving and some people connected we did remove the pure client check and when Mrmuppet connected he did have the xmas skins. He still seems to be stuck with the skin and has no idea where it is coming from.
Can you please connect to ip 37.187.79.49:27999 mrmuppet as uploaded a xp save file which he edited. Not promising this will work. If it does he will edit the one on etpub.
Password is test
If you connected to the server with out pb being enable you lose all your xp, You won't lose you level if you haven't been on the server for 6 months though so i don't know why you don't have a level if your using your old etkey.
