Look up the Peacock server for Hitman. You run it locally and it just does all the things the remote server would do, including tracking progression for you (this is independent of the progression on your actual account, though, since it's stored locally - IIRC you can copy your existing progress to Peacock, but obviously not the other way around). It's commonly used by speedrunners and anyone else who plays way too much Hitman, because it lets them actually just play whenever instead of when the official servers feel like working and because it's more reliable when running too.
