In the example shown below, lilypond is shifting the measure number (85) down, because it thinks there is a collision with the rehearsal letter "C". But in fact there is no collision: the 85 would be just fine in its normal position. This occurs only where a rehearsal letter coincides with the first bar of a system.
Is there a setting that tells lilypond, "Please ignore any supposed collision, and put the measure number where it would ordinarily go"? [image: collision.PNG] -- Marc Shepherd
