AH bug?

Yesterday, I've auctioned around 2 stacks of linen cloth and 2 greens. When I logged on today, they disappeared from the AH, and no gold from my mailbox.

And just today, I've auctioned 4 more stacks. I checked again after a few hours, and they've mysteriously disappeared!

I've been playing this game for more than five years so I know the basics of AH. What's weird is that some of my other items are still there and I receive gold when someone buys. Server restarts may have caused this...

You guys encounter this?

It's a bug we're aware of and already know the cause. Items aren't being lost, just misplaced.
The issue is already being fixed.
