I saved up simoleans and purchased the mansion, and have been using that house as the sort of community house for all my Sims. However, it won't let me add the fireman or sport hobbies. I purchased them, but when I go to place them on the mansion property, they're grayed out and unselectable. It will allow gardening plots, and I've removed plots, thinking that perhaps hobbies needed extra space but... The outdoor hobbies just don't seem to work at the mansion. Anyone experience this, or know how to make it work? I can add them to other houses.
