Nix is... not being reproducible ?

This is prolly one of the weirdest issue I have encountered with nix, but one of my packages is simply not reproducible. When i build the package on my PC i get this derivation: /nix/store/gjvii0k8jjwh42gq2dp8x7n8g2x9hzi0-twintaillauncher-unwrapped-2.5.2.drv But then when I build it through a github action to push it to my cachix cache i get this derivation: /nix/store/h2pjmazwx6n8k9rfwmjhy9kndl0g3jyl-twintaillauncher-unwrapped-2.5.2.drv This honestly doesn’t make any sense knowing in both case Nix is using the same flake with the same lockfile and the same package, so why would there be a difference ??? I have no idea what’s happening especially since it was working just fine right before and suddenly broke on its own Here’s the flake’s url: https://github.com/claymorwan/nurpkgs/tree/f1a9ebe3af17cfe5c317349393fca5709d83156b [https://github.com/claymorwan/nurpkgs/tree/f1a9ebe3af17cfe5c317349393fca5709d83156b] And the github action mentioned in here: https://github.com/claymorwan/nurpkgs/actions/runs/40935061622 [https://github.com/claymorwan/nurpkgs/actions/runs/40935061622]
