We're in the middle of testing the new housing. Check out this thread on the first test housing release and this thread on the second. Reading through the whole OP of each should help. The changeover to new housing should occur soonish, if the blog is to be believed.
Chocalte egg hunting isn't new. We had it last year. Sadly, I missed out on both years. Also, OP a lot if your stuff from your house may have gone missing in some bug.
