Android A book disappeared

[Steph91]

Hello,
Gunther offered me rewards and a blue book never made it to my inventory. I clicked on it and it vanished. My inventory wasn't full. I checked if I've read it but no, checked missing objects, Marlon, all my storage boxes...
I don't know if I will be able to get it again?

The same thing happened later with diamonds in a storage box. I logged in with the previous backup and it was back (but not the book).

Thanks

Blue books a.k.a. lost books never get into your inventory. The moment you pick one up it gets directly added to the Museum, where you can read them by clicking on one of the bookcase shelves.

Did it look like this?

Was it the dwarfish translation guide? You read that immediately when you take it from Gunther and gain the power to talk to dwarfs.
