What changed with the Mystery Box Upgrade and Easter 2015 updates?

Mystery box was super awesome for me. I just spend all my donuts on the beach house so I only had 2 to start. I bought 4 scratch off tickets and got 6 donuts for the first 3 and then score, 50 donuts.

I spent 60 of my 70 donuts and got:

Blue haired lawyer
Tire fire
Itchy and Scratchy billboard
A second Lard Lad Donuts
2 x 10 donuts
1 x 30 donuts
1 hot dog stand
1 bomb shelter
2 ponds

Still have 54 donuts. Stopped because I have all the premium items now. Definitely worth it.
