For April Fool's Day, the Chop Shop is now temporarily been renamed to the Unicorn Castle:
Car Parts are now "Magic Potions", and the vehicles are now different types of unicorns. Upgrading your Unicorn Castle will allow you to produce more glorious unicorns:
On a more serious note, this is a joke, so please stop sending me e-mails asking about the "new" Unicorn Castle feature!
I'm guessing this will only last one day, and that anything you end up doing to your shop should be saved during the transition.
Oh, and rackets players now have properties (thanks addycaissa!). Influence points have been refunded for stat points, however, some players have reported not getting their stat points fully refunded.
