Manually deleting the world folder every time one of your dumb friends dies in a hardcore sucks, so here it's the mod that does it automatically for you.

Everyone knows that the 1.20.1 is the go-to version when playing modded Minecraft. It broke my heart to realize that no one ever had made a mod that does this for a version this important… So I took matter into my own hands.

Whenever a player dies a 5-second countdown will start and when it finishes, the world will be automatically erased and reconstructed!

A 5-second countdown after dying.

Features

The world will reset without kicking any players or restarting the server.
It'll actually wipe region files, entities, POI data, advancements and player statistics, so there's not faking, it is for real erasing your world.
During the reset, all the players will be safely tucked away in a dimension that I called "The Limbo" in order to succesfully erase the world.
The mod keeps track of every world reset. Every time you spawn in a new world it will say in the chat how many attempts have you done.
Multiplayer & mod compatible optimized, the mod was made having specially in mind to play with friends and with mods.
