I wanted to add some info after my YDC Auction already had a bid on it.
I put in the new info, using the plain HTML box as usual, & previewed it, then decided I wanted to change the extra info slightly, so instead of saving the changes chose edit instead, & got a blank box, the previously added information had been wiped out.
I had expected it to work the same as when you originally list, preview & edit.
Auction ID 30213182
I've now redone my extra info.
