Error 404
by Whali
With Error 404, a world can start glitching in ways the game never intends, as a joke about code that goes missing.
What it does
Error 404 is a Forge mod for Minecraft 1.20.1 that turns the game into a prank-style experience full of unexpected, quirky and random surprises. It is built around the familiar Error 404 message and the idea of something essential suddenly vanishing from the code, and it is meant to catch players off guard for a laugh rather than to add new systems to play with.
The mod is published only for Forge on 1.20.1, with a single build, 1.0.1, released as an alpha on 2024-08-16. It is installed on both the client and the server, so the server and every player need it. The license is All rights reserved, and the code is not open source.
Key features
Unexpected world behavior
The world can behave in strange, unplanned ways that surprise anyone who expects normal Minecraft.
Prank-oriented chaos
The mod suits pranks on friends and adds a playful touch of chaos to an existing game.
Random surprises
Events are unpredictable, so no two sessions with the mod feel the same.
Alpha build
The only available file is an alpha release, so expect rough edges and possible changes.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Pranking friends
Players who want to startle a group can install the mod on a shared server and let the glitches appear on their own.
Who it’s for: Players who enjoy jokes, pranks and odd, unpredictable moments, and server owners who want a lighter, chaotic atmosphere. Because the mod is an alpha for one version, it suits people willing to accept surprises that may be unstable.
How it compares
Error 422 (safe) mod is a Forge mod for 1.20.1 that is installed on both client and server, under All rights reserved and not open source, so it shares the same loader and environment. I Don't See You also runs on Forge for 1.20.1 with client and server installs, under All rights reserved. The Error (Horror) takes a darker approach, with Forge and NeoForge files for 1.20.1 – 1.21.8 under the same environment and license.
