I missed most of the books that teach the Ranaar language in Acts 1-3. However, I've found all of the series scattered around the first level of Act 4. Yet none of them have any effect when I read them. So far I've tried reading them from the floor and from both inventories, and saving and reloading. I don't think it will prevent me from progressing in the game and I can kinda make out the Ranaar letters, but it would nice to be able to actually have the language translated. Any ideas why the books don't work?
