Hey, guys!
We finally smashed the bug that caused some of you not to get the Loremaster achievement even when you found every single note and phonodiary in the game. It can only happen in pretty rare circumstances, so that's why most people who found all notes got the achievement, and why we were unable to find the culprit for so long.
It's a Steam-only fix, so there is no patch.
To unlock the achievement, you need to read (or re-read) these two notes:
- Agatha Chertsey, Sophie's Big Friend.
- Unknown, Teleportation Test Subject #42.
If you already read them in your playthrough, you will have to play again and re-read them, unfortunately. Loading an autosave from the beginning of level 10 (Arx Vaporum) should suffice though.
Enjoy! :)
