The dedicated server previously picked a completely random seed with no biome diversity checks (the client validates but the server skipped it). On top of that, the client's findSeed() was hardcoded to only check a 54-chunk (Classic) area, so Large worlds had no diversity guarantee beyond the center. New server worlds now use findSeed() scaled to the full target world size. Added override-seed in server.properties to fix existing worlds without deleting them.
