Question

Entering a command to get a different seed than the one shown in the module's interface

Hello.
Were you trying to ask why the world seed shown on the Better Statistics Screen is different from the one shown by /seed?
If so, then the answer is simple: That's not the actual world seed, it's the SHA256 hash of the real seed, aka the "biome access" seed.

Here's how it works:

• Basically the server hashes the real world seed with the SHA256 hashing algorithm, which produces a variable called "biome access", and this variable is then sent over to the client for biome noise stuff (whatever that is, becuase I don't 100% know either).
• This "biome access" variable is then shown in the Better Statistics Screen menu when debug mode is turned on.
• As for knowing the real seed, that's impossible unless you have permission level 2 and can execute /seed yourself.

More info here as well:

• Minecraft Protocol at 0x28 | Play Client | Hashed seed | Long | First 8 bytes of the SHA-256 hash of the world's seed. Used client side for biome noise
