When I first started shopping for them, I couldn't understand why shops went into a "black hole" the month after I'd done them. They didn't show up on the status page as "approved," nor did they show up on the payment page. I checked with the help desk, and they explained that when a shop is being processed for payment, it falls off the assignment status page and won't show up anywhere in your account until it's been paid and is on your "payment history" page. Because this particular shop is still showing on my assignment status page, I wasn't sure it would be processed for payment in time for this month's deposit.
Happy to report that they got back to me far more quickly than I expected, and that shop will be paid this month. Go figure.
