Hello, I was wondering what version (23.05, 22.11, unstable, etc) of nixpkgs you use. I personally use unstable, and it’s never broken.
Edit: I also have a master input in my flake, which I added just for XIVLauncher (context: someone made a PR to fix it not building, and it got merged into master, but last time I checked it wasn’t backported to unstable)
I am using my own unstable nixpkgs, with nixmy (https://github.com/matejc/nixmy/blob/master/default.nix). Currently on 251 update of unstable channel :D I have my fork of nixpkgs: https://github.com/matejc/nixpkgs/tree/mylocal251
