Hey Mojang!
So the problem that I'm having is that when I try to join my world it won’t let me because I have add-ons in the picture below it says what I think maybe the issue.
Additionally all of my skins in game (not custom) have disappeared.
This may all be due to the new update but if you find a way that you can fix this then I would really appreciate it. Thank you.
What happens exactly when you try to join your world?
