Re: Apparently forgot to back second KS for Upgrade Materials - Piggyback possible?
Isaac mentioned on August 8th, 2017 in update #31 that the Pledge Manager will be locked at the end of the week, which has already passed, but apparently the project hasn't been locked (yet):

Your order is locked meaning that we can mail you your rewards. You can unlock your order to make changes, but make sure you get back to this page or your shipment may be delayed.
So, you better get in fast. Good luck!
