Money disappeared out of my Mailbox?!

I sold a bunch of 20x Linen Cloth stacks on ah YESTERDAY, and I seen that people bought them as it said "money not sent, pending until 12:00 AM" or something pretty close to that. Then I log on today, and there is not even one collection of silver/gold in mailbox, when I seen that at least 6-8 20x stacks were pending for 65s each? and I haven't even checked if other rare items sold that I may have lost a bunch more gold from?

I'm so confused as to what happened here, :S

Old issue never confirmed.
