Okay, so I did a bad thing. I set up a new Minecraft world, and I've spend about 3-4 hours getting everything set up, now I'm ready to explore, but I realize I've left level-type as default.
Is there anyway (I have MCedit if that's useful), to re-generate my world using Biomes O' Plenty, but keep any blocks I've places? I've not done much digging so I don't care if that resets, but my hourse, chests, farms etc I'd like to keep if possible.
Worst comes to the worst I can maybe move my base to a currently unloaded area, which I'd rather not but if it would work that would be good.
