I have placed an ad for a hangar9 Corsair for sell. My ads section shows two offers but I see only one. I received an email that I never responded to an offer but I don't see it.

You will receive an email explaining what happened.

Essentially, there was a hole in the system where guests could make offers without registering. As a result, you (and our system) would have no way to respond or know from whom the offer came. We have removed these from the system and fixed the issue. Sorry for the inconvenience.
