Historian Achievement

Wondered how many volumes of the History of the Living Lands people had found in the Eosthasian Temple. I have found 4 and the text itself makes it sound like 4 is the last one but I don't have the achievement so wondering if it is bugged or if there's a 5th book I haven't found!

I reckon it's bugged. I would imagine someone would have found a 5th by now.

I also have 4 and can’t find a 5th, but no achievement.

There are 5 books in total

Thank you, that last one was very sneaky.
