Generation Bug

[SupremeMortal]

When I generate the world for the first time, the chunk next to where I spawn always is buggy like this:

I have done this 5 times consecutively.

When this is the 0 0 Chunk, then change that, MCServer has some problems when the spawn is in that chunk...

im seeing this bug too

It's not a bug, it's a feature - a swimmingpool! 😉

I can't reproduce this. I've tried 5 times and each time the world generates okay.

Can you give me the world seed from your world.ini?

[NiLSPACE]

Most of the times it works normaly, but sometimes I get this as well.

[parabyte]

[Seed]
Seed=-723052804

[parabyte]

[Seed]
Seed=797167698

[madmaxoft]

I tried both those seeds, each with an empty world, and still they both generated alright. If you walk into that bad chunk and issue a /regeneratechunk command, does it regenerate properly or does it stay this weird?

[NiLSPACE]

When you use /regen it generates normaly.

[Masy]

not everytime, Howaner and i had a chunk (in the jungle/ocean, don't know if that matters) and it regenerated a hole chunk filled with warter until y = 64 everytime i executed /regen

[madmaxoft]

Could it be that only release-mode executables suffer from this issue? I've never actually seen this happen, and the only difference I can think of is that I'm always using a debug build.

[madmaxoft]

Finally, I got the bug! At least I hope so, because this one's massive:

All in all, about 20 chunks mis-generated. But this way it even hinted at what the problem is. The mis-generated chunks form a path from chunk [0, 0] in the X+, Z+ direction, randomly choosing which one to take. @tigerw sounds familiar? https://github.com/mc-server/MCServer/blame/master/src/World.cpp#L697-L704

[NiLSPACE]

Wow I've never seen it this big. It's usualy only 0, 0 when it happens to me.

[madmaxoft]

And after erasing the world and re-trying, the bug's gone again :(

[NiLSPACE]

Yea, as said earlier the bug occurs rather irregularly. :S

Well, it seems like you last changed it...
