Due to the change in the world generation method, I went and found a map seed that was suitable for using MCEdit to paste our old structures into it. The only problem is, there is a region around spawn (which I moved a ways from the original staring position using the editor) that is completely uneditable.

  • Blocks can neither be mined nor placed
  • Doors don't function properly (door splits between the top half and lower half, changes randomly when interacted)
  • Chests won't open.

Immediately outside that area, though, everything behaves fine. I don't know if the behavior is limited to a particular chunk or not. Could deleting something like session.lock work? Maybe a file permissions issue? Currently no one is using the server yet and have a backup of the world, so I should be able to fiddle with it with no risk.

Other info:

  • Minecraft 1.0.0
  • Vanilla server (no mods)

Any ideas?

  • @pppery Are both symptoms of the same cause? The questions are sufficiently different to warrant helpfulness for others, I think.

This is a feature of the vanilla minecraft server. Blocks within a certian radius of the player spawn are unbreakable to non op'ed players. This is so you can make a jail that somone connecting to the server will spawn in and only a op can let them out. This is to allow open servers but prevent drive by greifing.

I do not know if there is a way to turn this off. The best option is just move the spawn in MCEdit to somewhere outside of town.
