methods (Both report 0/0 world gen tasks). The only way to actually make the terrain generate is to trigger the chunk update.
I pre-generated a 16000x16000 area centered at 8000 8000 and the hole border is exactly at the edge of this pre-generated area (it goes along the Z=0), however later I generated additional 2000 blocks outwards so those chunks are certainly exist in the world. Also I was generating the world on a separate game server with Noisium and FasterRandom which are not present on the client.
