Hi Squad,

See how the third slur is misplaced here :

\version "2.19.15"

{
  \key a\major
  \clef "G_8"
 <<
    {
      | % mes.9
          <cis''-2>8*2/3( <d''-3> <cis''-2>) <b'-2>( <cis''-4> <b'-2>)
          <a'-2> %-\tweak color #red
          % here's the problem with 4th finger :
          (<b'-4> %% other fingering works fine.
          <a'-2>) <gis'-2>( <a'-3> <gis'-2>)
    }
    \\
    {
      | % mes.9
          a,2 <cis-1>
    }
  >>
}

\layout {
  \context {
    \Staff
    fingeringOrientations = #'(left)
  }
}

This seems to happend with 4th finger only (on v2.19, 2.18, 2.16 but not on
v2.14).

TIA,
Pierre
