Ok, sorry. The problem was this block:

  \layout {
    \context { \Voice
      \consists "Ambitus_engraver"
    }
  }

It looks like using an "Ambitus_engraver" with a \partcombine
results in that warning. I tried a \remove "Ambitus_engraver"
in the part-combined score but didn't work so I ended up moving
the \consist in each score in which I wanted the Ambitus engraver.
