I rebuilt the Foxbury Institute dorm house. The separate one and since then my student sim lives in it alone, no roommates show up or occupy the dorm. I tried it in different saves, the same thing happened. The cost of the dorm was more than 1000 simoleon per semester so not sure if this could be an issue but I am very bothered because the housing is beautiful but it’s very boring without roommates ☹️
