Every time I go to play on a multiplayer SMP server, I join, it pops me in, and then I fall into nothing and stand on nothing. It's all blue; all I can see is the sun and sky. How do I fix this?
This is likely just a slow server/internet connection. Have you tried waiting a few minutes? I find on my connection that some largely built and developed servers with many players such as the Reddit Server, loading the chunks at spawn can take 2 or 3 minutes.
