Cutting off the last few words or sentences of an article

I’m seeing this a lot vs it just being a rare occurrence.

Just using a basic prompt (using premium GPT-4 model) asking it to write an article for me about subject X.

It will write a nice article that I’m happy with overall, but…the issue is that very often it will cut short at the end of the article.

And by short, I mean often by just a few words, like it just doesn’t finish the last half of the last sentence. Or at most the last few full sentences.

I have to click “continue generating” or manually write the ending.

What’s going on here and how can I fix it so it completes each article?
