Minecraft wiki entry for Crash, associated text: Hopper is non-publicly viewable crash report utility, operated by Mojang, which manages, stores and maintains crash reports, originally exclusively for technical Minecraft troubleshooting. In 2019, its help articles were moved to https://minecrafthopper.net and all Hopper pages are redirected to the new site. This new site is maintained by the community and contributions are welcome in its repository on GitHub.
