Home Demolished.

I've been in a bit of a playing less phrase recently, but I religiously make sure to pop into my house and log off after the weekly cacpot lotto. Logged in today for some last min prep and discovered my home was demolished seemingly 4 days ago. I have NO emails or anything of the sort. has anyone had any issues like this and tips for how best to try and get it fixed. my empty plot is still there and everything. really really saddening if this gets swept under the rug
