Error Version
Error Version is a NeoForge cursed mod for 1.21.1 that adds a glitched dimension, eerie misplaced houses and unstable interiors to the Overworld.
What it does
Players open a portal from the Overworld into the Error Dimension, described as the origin point of the corrupted code. The realm has broken skyboxes, floating terrain fragments and a static-filled atmosphere. Dimensional ores and raw code fragments found there can be gathered and turned into top-grade equipment that cannot be obtained elsewhere.
Scattered through the world, House structures appear as misplaced buildings with claustrophobic hallways, shifting corridors and rooms that defy normal layout. Searching the floors of a House turns up glitch-tier loot needed for endgame crafting.
The mod is installed on NeoForge only, and the environment is client and server, so the server and every player need it. Builds are published for 1.21.1 alone, with build 5 of version 1.0.0 as the latest file from 2026-08-23. The code is under All rights reserved, so the mod is not open source. Error Version affects only the Minecraft world and does not modify files on the operating system.
