I know this is supposed to be for malevay suggestions, but thought it was worth posting as I have just seen this happen to someone. When you are selling something at auction and the item has sold. Take your nest into your inventory, set the price then re-rezz the nest. When you edit in world, the price defaults to L$10, and there are people who will buy the nest out from under you as you set the sale price. Just seen it happen and the person just left and ignores the seller and auctioneer.
