Unsaved Writings

I have recently noticed that just about every time my Sim leaves the computer and stops writing her books, it does not save and there is no "resume writing" option, except for one time, but I don't know what I did differently. In order for books to count, she seems to need to finish them in one sitting. 

I am playing on PC, with Lumpinou's Relationship Overhaul and Deaderpool's MCCC.
