I just got another little update

There's snow on Monsarno Research, Last Gasp Stage and Krusty's Clown College but still no snow on the Krusketeer's Set and Springfield Dog Pound (EA were so close on adding snow on every item). Maybe there was a fix with the mystery boxes and the dates for the premium items got changed with the update.

they can't fix it if they don't know about it

They had to fix starting dates on premium items as Baby Jesus' House w/ Baby Jesus was accidentally released a day early today.
