WordPress can’t remove ‘stop words’ on its own. You would’ve been using a plugin for this. I would contact its developers with your issue.
It doesn’t make any sense for hundreds of URLs to have changed at once. The only way this could happen is if all the posts were edited and saved with a new slug. The slug is stored in the database so it really shouldn’t be possible to change them all suddenly like that without intent.
The only other possibility I can thing of is that whatever plugin you were using wasn’t removing the stop words when the post was saved, but was doing it dynamically on every request somehow, and now that filtering has stopped. This seems like a really dumb way to go about this functionality though. Regardless, you’ll need to contact the developer of the responsible plugin to determine the cause.
I just wanted to follow up. I have not heard back from Yoast. Even if we go back and change the permalinks they revert back to the full URL on their own. Any ideas?

Also don’t use Everything WordPress for Fixing WordPress or plugin issues. This was moved to Fixing WordPress but your question really is for Yoast’s plugin.
