Playground Lot Type Missing
The Playground lot type, whenever I place it from the gallery, is replaced with a 'Generic' lot type. And when I try to use build/buy it doesn't show up at all. Now I do have a few mods, but no other lot types have been affected like this.
Try moving the whole mods folder to another place, delete the localthumbcache.package and then test to see if the issue remains without mods/cc there.
