I need a little help with some mods. I downloaded a few mods, I installed them to my Progamfiles(86x)/Steam/Steamapps/common/Simcity4/Plugins, but when I place them on the map they only show up as concrete slabe without the building. I would really appreciate some help on this, as I downloaded close to 50 mods and I don't want to have to delete them and reinstall, so any help would be much appreciated.
