Im using this mod from outside the steam workshop (when i had the workshop version i never got around to building one of these so i don't know if the same problem is occuring), and i'm finding your stone house which i invested quite a few resources in, is not getting populated with citizens, they outright refuse to live in it even when i force them out of other available housing, they'd rather be homeless. I can make due without it, but it would have been convenient for a kind of community housing option in high workload areas, like around quarries and mines. Also kind of obnoxious because i could have invested the resources and build time in several other housing options by now if i'd known it didn't work (but hey at least now I know).
I'm also using the most updated version of New Medieval Town mod which is the only thing i could think might be interfering, but all your other houses i've used from your mod are populating correctly, only this one isn't, which leads me to believe there's an issue with your code.
