Landoria ModSentry

Strictly validates required and optional client mods before a Valheim server accepts the connection.

Valheim compatibility

• BepInEx GUID validation
• complete version validation
• mandatory SHA-256 validation
• clear mismatch messages at the main menu with the affected mod and expected version
• complete server-side diagnostics

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.

Read the complete documentation.
