[Koha] links between bibs and authorities lost for custom authority types since upgrade from 3.6

[Fabio T.]

Hello Koha community,

a few days ago I upgraded a Koha package system (UNIMARC flavour) from 3.6
to 3.12: I really like the 3.1x series and everything went quite smooth
except some links between bibliographic and authority records being lost.

Now if I go to More › Authorities and search the authorities by type, I get
the expected search results but only the records belonging to the "bundled"
italian auth types are correctly linked to biblios in the "Used in" column.
I have created two custom authority types in the 3.6 system but according to
3.1x (the problem occurs in 3.10 and 3.12, not sure about 3.8) they are all
Used in 0 biblio(s).

I was aware of the warning for UNIMARC libraries upgrading to 3.10 and I
manually replaced non-UNIMARC values found here
http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=3087, restarted
Zebra, even did a full reindex, but no success. I quickly checked some data
involved in the linking within auth_header and biblioitems tables (like
biblionumbers, biblioitemnumbers and $9 in the marcxml fields) and they seem
to match with the ones in 3.6.

I've been scratching my head for some days and tweaked some more the Zebra
files but I had no luck, I also ran link_bibs_to_authorities.pl, and enabled
the CatalogModuleRelink and LinkerKeepStale sysprefs... but again, no
success. :)

Could you help me please? Obviously I can provide additional info if needed,
just ask!

Thank you very much.

Regards,
Fabio
