World Icon Updater

World Icon Updater is a compact client-side mod for Minecraft 1.21.1 that solves the problem of displaying world icons on the selection screen. Sometimes the game cannot correctly generate the icon.png thumbnail, and this mod fixes this situation.

Main Features

Automatic Icon Creation: If the icon.png file is missing or damaged, the mod automatically takes a screenshot of your world during gameplay and saves it as an updated thumbnail.

Fixing Old Worlds: For existing worlds where a standard or incorrect icon is displayed, the mod generates a new relevant icon.

Complete Automation: Everything works in the background without the need for manual intervention. The mod integrates into Minecraft's screenshot system.

Safety and Stability: The mod does not affect game performance, saved worlds, or gameplay, working completely unnoticed by the user.
