Not entirely sure if a bug or not, but - in 0.8.2b my Kerfur-Omega guide notebook just up and diappeared. I was holding it in my hands, switching between the game and notepad windows as I was trying to do a revision of materials I needed, and then suddenly the notebook vanished. I didn't drop on the base floor, didn't go through the floor (I did check the basement some time after), didn't end up in my inventory and it didn't respawn in the Bunker. I was thinking of simply reloading from last autosave, but as the thought occured to me, the game conveniently saved itself, and at this point this notebook seems to be lost to me forever.
...any way I can now reposses it on the same save file?
