There shouldn't be a ground. If you have a ground you need to use a different world generator. I am working on it this week as much as I can. Hopefully I will be able to test it on my server first and make sure I have fixed all the bugs I can find. Some tend to be a little harder to reproduce than others but my players have experienced a lot of the bugs mentioned here, even the one where they are spawning below their islands. So I will hopefully fix it up too. EDIT by Moderator: merged posts, please use the edit button instead of double posting.
