I was going through the group notices 'chiclets' (top right of screen), looking through and closing them. Two group notices sent by the same person (but to two different groups) had a notecard attachment. I clicked on both attachments. The notecards went STRAIGHT to the Trashcan instead of to the Notecards folder in my inventory. I could not find them in my Inventory, so did a key-term search and there they were in the Trashcan!
