Hi all, I just noticed that custom authority types cannot be used in automated authority linking. The details are at https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=26662, but I reckon it's a fairly significant bug in Koha. You'll never encounter it if you don't create new authority types, but if you do use new authority types, link_bibs_to_authorities.pl will never work correctly and C4::Biblio::BiblioAutoLink will never work correctly.
