Vigier Guitars

Hi,
I have a Vigier Indus, which is great, but I wonder what to do if the intonation of the A-string requires the bridge-saddle to move forward when it already is all the way forward? Are there any other options to shorten the string? The tone played on 12th fret is lower then the harmonic tone...
It's not a big issue, but I just wonder what my options are.

I would change my string brand because it means the string is not well made.

Strange cause it's d'addario 009 gauge although an old set. 

Very common...
Use Ernie Ball

I always used EB super slinky but I got nice deal for d'addario...
 
Anyway thanks for answering
