I thought it might have been a mistake on my part, but THREE times now while trying to make and hold reservations...they've disappeared after a day (before the deadline)

The latest was just today. I DID hold it and made sure it said it would be good until midnight (or 11:59p) tomorrow, as expected. Logged on to .bomb this evening and it was gone. AGAIN.

Searched through some threads and didn't find anyone else experiencing this. Am I the only one??
