Err873
Err873 is a Forge mod for 1.12.2 that adds cursed content, released in April 2025 by oblivionweaver.
What it does
Err873 belongs to the Cursed category and is built for Forge on Minecraft 1.12.2. Its only published game version is 1.12.2, and the latest Forge file, 3.0, was posted on 2025-04-18, two weeks after the first release on 2025-04-05. Installing it on a Forge 1.12.2 instance is all that is required, since no other mod is listed as a dependency.
Both the server and every player need the mod, because it runs as client and server. Clients and the dedicated server should carry the same build, so the server and players stay in step. The code is licensed under the Apache License 2.0, but the project is not open source, so the source tree is not published under an open license.
Among the 150 Cursed mods with Forge files for 1.12.2, Err873 is one of the options for that combination. Players who keep a 1.12.2 modpack can add it without moving to a newer game version.
