What happens when you rejoin world (or server)? Can you see this structure normal? Perhaps it just not rendered.
Remove your sprodump folder.

no its actually in the world. I will remove the dump files.

Can't reproduce. But I've got it one time in 1.7 version, so it still opened. Thank you.

It's not because of sprodump folder. It's a world chunk-generation problems.
And I also tested biomes o plenty and it works normal.

Okay so I am finding serious world generation bugs ... can you help figure this out?
@ternsip I am checking with other mod authors as well people who mess with world generation code.

Okay @ternsip I can confirm its serverside issues only. Please double check server chunk generation code.
That deathstar would have been cool :(
