Bumping an old thread, but I was going crazy trying to find a solution for Alive not working with RHS units until I accidently stumbled on a solution.
When you copy ctrl +c the faction names from the Alive wiki it adds an invisible character at the end (newline or something). So when you paste it in game it won't work. Just mark and delete the last (invisible) letter and it will work (did for me at least).
