Noir is standalone so the only Companion that goes with it is the Deadlands Noir Companion which is in that same dataset. You might be able to incorporate stuff from the Horror Companion if you really wanted to, but largely I'd suggest running Noir as is since I think it's built pretty well the way it stands. One of my personally favorite settings (although I may be biased being from New Orleans
), with only Hell on Earth beating it out for me.
I'll take a look at the date file later and put out an update to fix that. Definitely let me know if you see anything more like that. There's always stuff that gets missed with all the copy/paste and retyping of stuff into a data file.
