August 30th to October 4th. Get 4 times the payout for the Heights crafting buildings.
I've managed to finally upgrade my first Private Island to level 5, buy 2 more, and I'm almost done with the Exclusive Resorts.
That's the Furniture Shop, Coffee Shop, LA Body Works, Institute of Technology, Pharm-er John's Pharmaceuticals, Marketing Agancy, and Heights Theater.
Sending 5 regular characters gets you 20 crafting currency. If you have the 6th Premium character it pays out 28.
PLUS! The Googleplex runs for FREE! Every 3 hours get 20 extra currency of your choice for FREE!
The PolyVac and Insanity Cauldron are also also paying out extra currency.

Well apparently the Googleplex being free was not intentional, so they fixed it with the latest patch a few minutes ago.
But how long do they let bad glitches go on unfixed?
