Hi,
I noticed it on this story in the first part:
http://archiveofourown.org/series/148518
Each part is one chapter and about 45k words.
The odd part is I've read stories from months ago that are structured the same but I don't recall parts of the story dropping off mid-sentence.
I may need to go back and see when this began to happen. I haven't changed readers. I'm still using the Sony PRS-T3.
I'll consider the option to manually convert the stories. I don't think the short stories will need it or the ones that have short chapters.
Thanks,
Amalthia
