[ARCHIVED] Routing/Sit down issue on several interactions

Whenever my sims read a book in their house (not sure if this happens in the library, I think it doesn't) they'll leave it on the table (when they're done). When I try to put it back to the bookshelf my sim will always grab the book, sit on the closest chair (as if they were going to read it) then get up again and go to the bookshelf. I'm playing on a Mac, not using mods or CC.
