Field sequence mismatch errors on MIT Discursions (both sides, all areas)

(probably a regression) - looks like field14 detection is bad through the disk.

Confirmed regression - the phase offset is about 90 degrees and the new code doesn't know what to do with it. Will probably apply to the National Gallery of Art disk too.
