"Unfortunately Ben, who's the mastermind for the patches, was taken ill and had to go home early before he could complete the patch creation process. Rather than have someone else take over part-way through, and risk screwing up what he'd already done, we opted to put the tested standalone version in the marketplace today, and let Ben complete the patching on Monday when he's recovered."
Of course, we assumed that Ben would be back on Monday. He's still unwell, so we're having to delay the release of the patch a little longer. In the meantime, you can still get the pack from the Marketplace.
