This works exactly as intended. The error is self explanatory.

Use NBTExplorer, open your level.dat and change largebiome for normal.

Very helpful, thx!

@dktapps A note here about previous discussion on this topic. Many server owners are likely to be using custom generated worlds, where the original generator is not available, and the server owner expects that PocketMine will not be able to continue generating matching terrain in new chunks.

An option in pocketmine.yml under the worlds section, where server owners can override this behavior per world, would be preferable to having them try to update their maps with an NBT editor.

@dktapps
I agree with @95CivicSi as most of the worlds i have loaded for Factions are custom terrain made with PC Mods. I get the reasoning behind this, but it needs to be toggleable.

[CupidonSauce173]

I do not understand your points @LegoFan48737 and @95CivicSi, using mods / custom world generator, MCPC maps made with EpicWorldGenerator for example, all of these aren't working on pmmp. Means that if you throw your world in ur worlds folder, when you will reach the end of the mcpc pre generated world, it will just start to gen a normal world. As said yesterday, just use NBTExplorer and change the .dat settings for normal, this is what I did or just make a hacky patch if you want it to work.

[CupidonSauce173]

It takes around 15 seconds per world to change a a .dat using ssh connection with bitvise.

@CupidonSauce173 For now we will, but that process could get old. BTW, does the generator name need to be normal or something else?
As for PC worlds, if you get a custom terrain, use Nukkits worldfixer plugin, then upload to your PMMP server, they worked perfect before this update, especially when most of said worlds were configured to not auto-generate terrain.

[CupidonSauce173]

@LegoFan48737 needs to be normal, in fact, only normal is allowed now, I think flat and void aren't too.

[dktapps]

The known generators are normal, default (same as normal), flat, hell and nether.

I am aware that this bug fix has caused some disruption for users of custom maps, and I'm investigating a solution involving a superficial runtime generator override. For now you should use an NBT editor to change this. If you want void-like generation, use the flat generator with a preset of 2;minecraft:air;1.

Can u justify how was it intended to be I mean how am I supposed to upload world ?
