We're waiting for Apple to approve 1.2 for the App Store. Until mobile is updated, any Weapon Cubes earned on Steam will be lost if you load the save on mobile. Don't Panic! If this happens, just post here, we'll make sure you get your Weapon Cubes back! EDIT: Sept 14 Update 1.2.0 has been released on iOS. Make sure version 1.2.0 has been downloaded & installed then you should be good to use Weapon Cubes on your Apple device.
