I don't know can we/you manage to link all the orders with payments since there was no obligation for group buyers to buy from wallet address they used to collect funds, and some also used escrow?
SebastianJu' batch #2 was paid, and order status was changed to "chips ordered" as per Sebastian's OP, but I will let him know about this so we can "hear" what he "says" about it.
I have to clarify that I have full confident in Sebastian and I appreciate all the effort he did to justify his role as group buy leader, so if anything wrong happened I would see it as mistake and nothing more.
Oh, I think you understand me wrong, there is the payment for batch #2 ->

There is a big gap on this addresse between 2013-05-11 14:57:58 and 2013-05-22 02:17:07. Seems there are actually more orders than the 97 batches on 1FGAftzSTztFSB8LMwsrdCKTyqGY6zr3sU.
