Checked my account tonight (I had earned two Cat 4 night certs.) They both showed unused--until I recently attached one to a reservation.

Checked account tonight. The unused one is missing. The attached one is now "detached" and vanished. I called Plat Res. They show both certs unused on their side. She mentioned weird system problems today. I told her I would call MR tomorrow to sort out.

Very strange. Might want to check your certs.
