I loved this mod but there was a few things missing, for example and children's room because i wanted a family to live there with me. So i made an identical room to the master suit with children's beds, lighting, navmesh and all and saved it. I went to edit the interior more and change how the guards looked but there were two world spaces the one i made with everything i changed but without the parts that were already there. I don't understand why this has happened i saved the interior world space but it split them. I tried again and it happened again. Does anyone know why? Its really bugging me because i want to play skyrim again, i cant let this beat me. Any help would be wonderful thank you.
