I ended up just rewriting the article, but thank you so much for getting back to me!
For anyone who is looking this up in the future (I know I went through every forum page that looked even remotely like the problem I was having), I had saved a few times before it erased the post, but when I finally was able to find an older version in the drafts section, it had only about 150 words of the original 1500 word article. There was never a pop-up saying that my browser had a backup, and I was never able to find what happened to the original. The revisions option only appeared later, after I had saved my progress on the new version, and had only two options: the version I had just saved, and the original 150 words it had recovered.
Thanks again, and from now on I’ll be backing up my posts in an offline document!
