Due to an error in the creation of the books, there were a few positions with mate scores in the books. (https://www.sp-cc.de/uho_xxl_project.htm)

I guess it's okay to just replace the books with the corrected versions, since they haven't been used on Fishtest yet?

The old UHO_XXL books are also affected by this very rare error. I can also create a PR for them, but first wanted to ask if they should simply be replaced.

yes, I think it is fine to replace also the old books.
