I set my chapters to 5,000 words, but they come back at about 1,500. Why, and is it fixed?

Yes, from version 1.9.24 long chapters reach the length you set. Before, a long chapter was written in a few large pieces, each piece was accepted even when it came back at half its size, and the AI was asked to be concise, so a chapter set to 5,000 or 6,500 words often came back at about a quarter of that. Now a chapter of more than 2,000 words is written in sections of about 1,300 words (a 6,500-word chapter in five sections), each with its own share of the chapter's plan, and only the last section ends the chapter. When a section or a chapter comes back short, BookyAI asks the AI to continue where it stopped instead of accepting it. Chapters written before keep their length: to bring one up to its length, regenerate it from the book's page (hover the chapter's row and click the Regenerate icon). Its old text stays in the chapter's Versions.
