Ask HN: Did I just break HN?

Howdy. I just tried to post the latest chapter of Crafting Interpreters by Bob Nystrom because I didn't see it posted yet. Unfortunately, the first time I tried I thought I did it wrong, and deleted it (Thinking it should go on 'Show HN', but in my ignorance I didn't realize that that was just a convention put in the submission title.) I tried to re-post the article link [1], but HN says its already been submitted and shot it down. I feel like this is an error, because I can't find the link posted anywhere after looking manually and using this search tool [2]. Help?!
