I need a Plugin that detects and deletes unmodified chunks so that they regenerate. It doesn't matter how much cpu/ram it uses.
@Gagootron Could you define "delete" in this case? And finding unmodified chunks is tricky, won't be flawless.
@timtower Well i want that the chunk wich was generated in 1.8.8 gets the new 1.9 structures. And also i want to save some space on my harddrive
