Transposing instruments handle difficult key signatures incorrectly
Score is in B major, in concert pitch, and includes an Eb clarinet part. In order to avoid 8 sharps, the key signature of the clarinet part switches to Ab. However, accidentals still remain as if it were G# major. If these are manually changed, the concert pitch score now shows up as is the Eb Clarinet is in Cb major.
This has been a problem since 2.x I believe, but am not sure
