Lost_procedure
by Xcreeper
Lost_procedure is a NeoForge cursed-themed mod for 1.21.8 whose content is built around corrupted system text, glitched textures and fatal error messages.
What it does
The mod is framed as an unfinished, corrupted game process. Its text and assets are styled as system logs and error dumps, with strings such as CRITICAL_ERROR, SYSTEM_CORRUPTED and FATAL_OVERWRITE, and some textures are marked as officially corrupted. A server running it needs every connecting player to have it too. Multiplayer is supported, though the author recommends playing it solo first. The only build is for 1.21.8 on NeoForge, and the mod is released under the MIT License without being open source.
