Hello fellows from mojang. I have recently experienced a bug, I got a new pc and im not sure if its because of this but whenever i change my skin model to slim, ingame i shows as as classic, i have no clue why it does that i have tried everything restarting the game, the launcher and even uninstalling and installing the game. If you could please be very kind and fix this bug thank you.
