♥ The only person allowed to post regarding an auction ending is the auctioneer. Posting to deter other people from bidding is not allowed, even if you think you've won and the auction is over. If you calculated your time wrong, this confuses all bidders and the OP misses out on bids.
You are right regarding the auction ending but be sure to follow the auction house rules! :)
You have won Eurydice for 70 bones, as well! I'll email her over as soon as they are received.
