Devastated!

HEART PAIN!
I went to delete my main room thinking I could build a nicer one BUT once that room was gone, the house value went down and I couldn't build anything part from square rooms *faints*

To make matters worse, the main door became attached to the toilet and can't be removed now :'(

Arghhhh very sad! Some of my wallpapers also disappeared :/
Seems like there's no way to salvage matters. Might as well restart if that's possible...

I'm talking about Sims Social by the way.
