This is a known bug in version 5.0.0. It affects players who: A) don't own the New Neighbears DLC, and B) are either early in the game (prior to meeting Veggie Bear) or are later in the game but playing in languages other than English or German.
We have fixed the problem in version 5.0.1, which is now live on Steam. It may take a while before players on other platforms receive the fix because of porting and certification. Don't worry; the missing text isn't anything important to the story—it's some randomly chosen babble about scrapbooking, friendship, or a glowing sky. In fact, if you're a long-time player then you've probably seen it many times before.
Q: I see a similar problem but it's a different number than 27
A: The fix mentioned above should fix things for you, too. There are a number of affected lines, of which 27 is the one that people are most likely to encounter, which is why we used that as the example. The only important affected line teaches you how to run, which you can instead read about here.
