Memory Loss
by crraaft1k
Memory Loss is a Fabric survival challenge where crafting recipes are forgotten at random over time, so a player can end up unable to craft basic tools.
What it does
Over the course of a run, the mod periodically makes a random crafting recipe disappear from the player's knowledge. Recipes forgotten this way are restricted to weapons, tools, armor, swords, pickaxes, helmets, shields and similar gear. Crafting tables, furnaces, chests and torches are never forgotten, so a player can always rebuild a workspace and light a base. Each recipe is lost with a clear moment in play, which pushes survival runs toward finding other ways to get the gear back.
Memory Loss needs Fabric API. Every player and the server need a copy of the mod. Files are published for Fabric only, for Minecraft 1.21 and 1.21.1, with the latest file 1.21-1.21.1-1.0-fabric for 1.21.1. The mod is released under the MIT License and is not open source.
Key features
Timed recipe loss
Every few minutes a random crafting recipe is forgotten, so the forgetting builds up across a single survival run.
Essentials stay craftable
Crafting tables, furnaces, chests and torches are excluded, so basic survival blocks can always be made again.
Visual indicator
A small indicator in the top-left corner of the screen shows how many recipes have been forgotten so far.
Synchronized server state
The server tells each client exactly which recipes are forgotten, which prevents desyncs and ghost items in multiplayer.

Use cases
Who it’s for: Players who want a survival run with a memory-based challenge, and server owners who host shared challenge worlds on Fabric.
How it compares
Random Crafting Recipe is the closest option: it works on Fabric, Forge and NeoForge across 1.12.2 – 26.3, and its license is the MIT License. Only the client needs it, and neither side is required to run it. EntropyMod is a Fabric mod for 1.21.5 – 1.21.11 under a custom license, and the server must run it while clients may leave it out, so it is not open source. Daily Heart Loss is server-side only, MIT licensed and built for 1.21.4, so players join without installing it.
