Continue button, not showing up in story engine when he AI pauses

I noticed one time when the AI in story engine paused for an extreme length of time during the chapter creation, a continue button option popped up at the top. However, out of the four chapters, I've tried to have it right so far, three of them paused near the end, mid sentence. And no matter how long I waited I have never seen a continue button option pop up. I've refreshed the screen. It seems like the only way to get it to continue would be to actually rewrite the entire chapter and waste a ton of words. it needs to be able to recognize that the AI did not complete, and populate that continue button option so that a user does not have to waste all their words rewriting chapters just to get it to finish. Especially if I'm only getting it to finish 25% of the time.
