I checked the code and if it gets to a position that's not in the book then it will stop checking the book for the rest of the game. So it will miss cases where the game transposes back to a position that is in the book. Could this explain the problems you're seeing?

After some additional testing I found two more issues with the book code and I think there are still more that I haven't found yet. I clearly haven't tested this code enough. I'm working on a few other things at the moment so it will take some time, but I will at least make sure to fix this before the next normal release.

Thank you for reporting this issue.
