Bukkit

What steps will reproduce the problem?
1. I'm standing on a chunk.
2. I use /chunkfix.
3. The chunk regenerates to its original state.
4. I fly away.
5. I fly back.
6. And now it's there again.

What is the expected output? What do you see instead?
I remove the chunk, and when I fly away it's okay. But when I fly back, and the map renders
again, the chunk is suddenly there again. And I've tried hundreds of times, but the chunks I
rollback always appears again.

What version of the product are you using?
I'm using ChunkFixer v1.0.
And I'm using Craftbukkit 1.2.5-R4.1

Do you have an error log of what happened?
No, sorry.
