Hide Downgrade Warning
by UnknownKing
Hide Downgrade Warning removes the prompt that appears when a world saved by a newer Minecraft version is opened in an older one, so the world loads directly.
What it does
When a player opens a world last saved with a newer release, Minecraft normally stops on a warning about downgrading and an unsupported version. The mod hides that screen, so the world opens right away. Nothing is changed in the save itself, and the mod adds no commands or settings to tune.
The mod works on the client alone. Only the player's game needs it, and no server configuration is required. It is a Fabric mod, and files cover 47 release versions, with 1.0.1 as the latest build for 26.2 published on 2026-08-13. It is open source under the MIT License, and its source code and issue tracker are public.
Key features
Automatic warning skip
The downgrade warning is suppressed automatically whenever a world saved by a newer version is loaded.
Direct world entry
Players enter the world at once, without confirming the warning screen first.
Light startup cost
The mod is small and adds little to the time it takes the game to start.
Save files left unchanged
Only the warning is hidden, so the world data is not altered by loading it.

Use cases
Playing an older install with a newer save

Who it’s for: Players who regularly move between Minecraft versions and open worlds saved by a newer release, and who prefer not to confirm the warning every time.
