World creation is incredibly slow for seed -6594452106484986840

World creation with the seed -6594452106484986840 takes much longer than the average seed. Where the average seed takes my computer about 15 seconds to get from clicking "Create New World" to being in game, this seed takes about 1m 30s - 6x slower.

In addition, it takes another 30 seconds once in game until new chunks begin to generate. The chat is also completely unresponsive during this period. After this initial period of slowdown, everything seems to work as normal.

This only affects world creation. Exiting and reloading the world behaves as you would expect.

Just wanted to chime in and I've been doing some seed hunting on 21w37a last week this also happened to me on a small handful of seeds I generated. Unfortunately I didn't keep track of the seeds. I'm continuing to seed hunt and will post any other seeds that have this issue.

You can add that this bug also affects version 21w37a.

I launched up an instance of 21w38a with the seed you provided and found out that the spawn location was in the middle of the ocean. While this is intended as stated inΒ MC-142883, the lag created when spawning in this environment isn't, therefore making this a duplicate ofΒ MC-236858. πŸ™‚
