When a player is joining a world their inventory isn't saved and everything is lost, only the one hosting the world has their inventory saved

This is when reconnecting, and we are aware of this issue. The thing is that the server currently doesn't identify players. This will be fixed at some point in the future.
Richard, what you are describing is entirely unrelated to this issue.
I am a well-established player on my community server. I logged off on Friday evening, and logged back in shortly afterwards and I found myself at spawn with none of my items on me and my Enderchest empty. I did not join as a new player. Rather, my character data was affected by this bug which screwed me over.
I'd prefer that Mojang raised the priority of this bug. It can be quite crippling and frustrating, especially when it happens twice in the span of two hours as it did to me.
This is not a bug... If you join another players seed of course you will not have anything in your inventory. Get your friends to craft some extra tools then join them.
