Everyone on a multiplayer world shows up as a steve skin. In your own inventory or third person view, you can see your personalized skin, but to others, youre also steve. We had a previous skin glitch where you would appear as eachothers skins. Apparently, when you tried to fix this bug, you accidentally changed it, rather than fix it. There were a couple weeks of no problems between these 2 glitches, where skins worked normally. Please fix this steve issue.
