Landoria ModSentry

Guarantees that every player uses the same approved mods, versions, and files, so everyone enters the world under the same conditions.

Valheim compatibility

• Checks every player's complete mod setup before they enter the world.
• Allows only the exact mods, versions, and files approved by the server.
• Returns the player to the main menu with a clear explanation when a mod must be updated.
• Gives server administrators complete diagnostics for resolving mismatches.

All other client mods are rejected. If a mod does not match, Valheim returns to the main menu and explains what must be updated instead of remaining on a black loading screen.
