Crash when login with client on linux

[Carlossg]

Fixed a problem with the Core teleport function.

Hm. Carossg, did you or your friend try to use a special inventory feature (eg pressing number keys to change where an item is in your hotbar)?

MCServer doesn't currently support that particular feature.

You may also have tried to craft an item whose crafting recipe was not implemented yet.

The message basically means that the server side inventory didn't match your client inventory because an item got there / disappeared when it couldn't have.

Oh, yes, was that, I didn't now that is not implemented yet, sorry

Edit:Still happens with doors;
