Do you mean that you feel like your Midnight Hollow town should automatically have everything in it from all the expansion packs? Like when you load the town, did you expect to find the discos etc already in that town? Each town is unique, so if you want things in your Midnight Hollow town, you have to place them in the town manually. For example, if I wanted a nightclub in Sunset Valley (base game town), I'd have to go into Edit Town and choose community lots, pick the nightclub I wanted, then place it on an empty lot in the town. Is that what you mean?
