Minecraft LAN Worlds = Players Having Steve Skins

Whenever you have a single player world and open it to LAN, the multiplayer's skin will either be a steve skin or my skin will be a steve skin. Either way our actual skins will not show and only the steve skin will show.

The only way to fix is to upload a custom resource pack with our own skins titled as steve.jpg.

It has been an ongoing problem for myself and others for quite a while now.
