Yep, I've had that happen, too, which is why I wasn't all that concerned by it. (Shocked and amazed at the quantity/quality of the sound, but not terribly concerned the first time it happened.) I expected them to drop back again, having been so flat. If I suspect the block is really awful, I'll leave my hammer on the pin, just to make it easier to see if the pin turns back when I let up on it. Unfortunately, I didn't do that this time, so I don't know if that was the culprit. But it's the cluster of strings whose pins I never even touched that worry me. Why did they drop in pitch so precipitously -- simultaneously and without apparent cause? Believe it or not, I'm not discounting the suggestion that it was just jumpy pins. Just pondering out loud........
