This has happened twice since I updated (and got the pets and other great new items.)
I got coins for the things that were sold, but I did not drag them outside the gate.

The first time this happened the store screen had just closed, the "Decorate" tab was open because I had purchased a rug and I touched the wide cabinet. Poof! I got the message sold for xxx coins and it was gone. I didn't move it outside the gate, didn't even move it in the room, I just selected it and it was gone.

The second time this happened I was rearranging furniture in the blue bedroom. I selected the doll it vanished and I got the message that I had sold it.

I am playing on an iPad2 and just updated it. (I am loving the new pets, toys and other items, but I am nervous about rearranging things now.)

My apologies, Heidi!

Had you recently sold any other furniture or decor items, before purchasing the rug (or before rearranging furniture the second time)?

If you don't mind, I'd like to ask you to please submit a support request on our help desk page. We can provide a temporary workaround that requires working with you one-on-one. We're very sorry that this bug slipped through, and we want to make sure that you get what you paid for.

Thank you!

Thanks for your reply.

No. I have sold items before (and since) but not immediately before those instances.
