ErrorsNStuff
by jcmcc
ErrorsNStuff, a Fabric mod for Minecraft 1.21.11, adds intentionally broken, error-themed blocks and items to the game.
What it does
The mod introduces content styled as software errors and missing placeholders. It includes an edible Error Item, which represents a game error and is meant to test food mechanics and edge cases, and an Error Block that stands in for missing or unfinished content. Its mechanics are deliberately unusual and unstable, so it is aimed at testing and play rather than balanced survival progression.
Installation needs Fabric API on Fabric. ErrorsNStuff runs on client and server, so servers and players both need it. Its only published build is the 1.21.11 file for 1.21.11, released on 2026-01-30 on the alpha channel. The mod is released under the MIT License and is not open source.
The author notes that content may change significantly in future updates and that placeholder behavior will shift as development continues. Some features are experimental and may be altered or removed.
