I'm in need of something. I've got an enormous area with thousands of water source blocks I need to clear. Anything out there like MCEdit that will work?
MCEdit should work fine with mod blocks, it just displays them as unknown pink blocks and leaves them alone; I used MCEdit to repair a Technic MP map during 1.8.1 when some strange chunk corruption appeared. Did a recent MCEdit update introduce a bug where it deletes unknown blocks now?
