I found this weird bug when I do this, When I let myself go afk on the Hypixel.net multiplayer server it take me to a world an displays text on the screen saying you are afk. When I disconnect from there and go into a single player world that text stays there even when I go in and out of the world. It only goes away if I connect back to the server then leave again, without letting it go back to the afk thing on there. Or if you close the game then open it . It is repeatable.
