I have a Minecraft save (SMP) that has a very sudden shift in terrain and biomes. To be exact, there is a long line along which the maps shifts from one block to the next in terms of natural terrain and biomes.
This is looking terrible, especially on my world map. I've googled for this issue, but can't find any result where this issue is addressed. While looking for a solution, I read some mention that if you delete chunks in MCedit and let the game regenerate them, it will generate exactly the same blocks, so that is not an option. If MCedit can help in any other way, that's cool, I know my way with the program a little.
Some info: I think the world was generated in vanilla 1.7.1 or 1.7.2. I'm using mods now, but not at the time I started this world.
Is there any way to change/fix this?
