I believe I encountered a bug with this mod that caused the stage coach to only spawn class mods that were installed with and after this mod. When uninstalling and advancing a week, all classes started appearing again (when for 10 weeks prior only 4 class mods spawned). I have not installed any mods that should alter the spawns otherwise. However, I have also upgraded the stage coach network on the same week that I uninstalled this mod, so perhaps it was another issue entirely.
That said, I only had the Acolyte of Sun when I installed this (and still do), so perhaps that is somehow linked. I apologize if my troubleshooting concerned the wrong mod but I thought I'd comment this in case anyone else encounters a similar issue.

For some reason this doesn't seem to work for werewolves in my current game. The Shattered Estate only shows "Acolyte of Sun, Phantom" and then lists the effects. There is also no other district that the werewolf benefits from. My load order should be correct, since it does work for the other two classes...

No

does this require all 3 of the character mods
