Description of bug

Happened: Cache miss

this derivation will be built:
  /nix/store/9cwvqgrj4m4j76diimgp9fzygxrr8zpd-freesmlauncher-unwrapped-de60a60.drv

Expected: Cache hit (this path will be fetched)

Steps to reproduce

1. nix build github:FreesmTeam/FreesmLauncher/de60a60512a001ac3683c35f7b1c5122d58d891d#freesmlauncher-unwrapped --dry-run --accept-flake-config
2. Observe the NAR mismatch from garnix (https://garnix.io/build/9vGj3G6g)

Suspected cause

Impurities caused by Git (I did with flake-compat and cachix and I got cache hit)

This issue is unique

• I have searched the issue tracker and did not find an issue describing my bug.

For anyone who wants to use binary cache now, change the url for the freesmlauncher input to https://github.com/FreesmTeam/FreesmLauncher/archive/develop.tar.gz, comment out inputs.nixpkgs.follows = "nixpkgs" (recommended to not break reproducibility, but you may experiment with it) and use cachix instead of garnix like so:

{
  nix.settings = {
    substituters = [
      "https://freesmlauncher.cachix.org"
    ];
    trusted-public-keys = [
      "freesmlauncher.cachix.org-1:Jcp5Q9wiLL+EDv8Mh7c6L9xGk+lXr7/otpKxMOuBuDs="
    ];
  };
}

comment out inputs.nixpkgs.follows = "nixpkgs"

using it might as well break cache
i'm not using it at all:

{
        freesm = {
            url = "github:FreesmTeam/FreesmLauncher";
        };
}

You use github: URL syntax, use tarball to not expose rev
