Yup it was still around for the people who hadn't done it yet. I actually made 98 crystals off this challenge. Got my giant warehouse for 31 crystals then moved my crane warehouse in and out of inventory to get a further 129 crystals.

So essentially I got a giant warehouse and 98 crystals for free :)
