API finish reason not reporting "length"


I’ve just noticed that API is reporting finish reason as “stop” when previously running the exact same script/code it would report finish reason “length” if the response was not complete/full. This is important to me because the code generates chapters for a book, previously I was able to use this finish reason to tell the API to continue from where it left off, now it never reports finish reason as “length”, this started happening over last few days.

Is anyone else having this issue?
