how do I develop the rehad center? havent come across it yet with the up dates
one of the areas you can conquer allows you to build it
i don't remember which one though
You have to collect materials in the northern district, once you have enough it will let you build it there.
Investigate the district north of the manor; you'll come across an empty plot of land that you can have the rehab center built on once you get enough materials and get the builders in the district south of the manor back working
