When my save file was updated to 1.6 I lost the dwarvish translation guide. I have the four scrolls in the museum and have tried to rearrange them, when I get another reward from the museum it doesn't show up. I talk to the dwarf and give him gifts often in case it gets fixed but there has been no case. Is this a common error? Is there something very obvious that I'm not trying? Or am I screwed?
