Possibly incompatible with Lithostitched

[RaviScriptDev]

Install the library mod "Lithostitched" in a Fabric environment using Minecraft version 1.21.11, try to open a world and you may see the following crash message:

It’s a known issue. :)

Btw it can be fixed by unzipping or extracting the mod, opening pack.mcmeta which should look like this:

    "pack": {
        "description": "Lithostitched resources",
        "pack_format": 48,
        "supported_formats": [48, 99],
        "min_format": 48,
        "max_format": 99
    },
    "neoforge:overlays": {
        "entries": [
            {
                "directory": "overlay.breaks_seed_parity",
                "formats": [48, 99],
                "min_format": 48,
                "max_format": 99,
                "neoforge:conditions": [
                    {
                        "type": "lithostitched:breaks_seed_parity"
                    }
                ]
            }
        ]
    },
    "fabric:overlays": {
        "entries": [
            {
                "directory": "overlay.breaks_seed_parity",
                "condition": {
                    "condition": "lithostitched:breaks_seed_parity"
                }
            }
        ]
    }
}

Then remove the neoforge:overlays and fabric:overlays blocks so it looks like this:

    "pack": {
        "description": "Lithostitched resources",
        "pack_format": 48,
        "supported_formats": [48, 99],
        "min_format": 48,
        "max_format": 99
    }
}

And finally rezip the files (not the extracted folder, the files inside), and rename .zip to .jar
