[Hairy Hippy]

Edit: Doesn't help it's late!  I've now realised how this is done.  SORRY!!!

The reason for the below crossed-out stupidity is because in the UK we have "12A" and "12"...  They are basically the same.  Why BBFC introduced "12A" is anyone's guess but it makes zero difference... a "12" is a "12"; if the parent allows below a 12-year-old to view, it really is their prerogative...

I prefer to classify in line with guidance and have the common sense if I think my child is capable of viewing it 

I did change the "Core.Mapping.Certifications" for 12A to 12 and enabled multi-scraping renaming and all worked a treat  

I'm on a roll... Sorry!

Certifications vs MPAA for non-USA users is the same.  I know that if I select say "UK" under MPAA in settings, it will make the MPAA equal the UK Certification but it doesn't automatically place it in the "Certification" field always.  Yet the Core.Mapping.Certifications file is based on the Certifications field not MPAA.

There is no Core.Mapping.MPAA file...

Can there be a mapping or setting that makes these the same?
