Hi Frank,

\RemoveEmptyStaffContext is deprecated and you will not find any entry
about it in the NR of "2.14.2".
Well, for reasons of compatibility you'll find the old definitions in
engraver-init.ly, so I wonder why it doesn't work.

But if you switch to the new syntax:
\layout {
  \context {
    \Staff \RemoveEmptyStaves
  }
}
it _will_ work.

Attached mwe-rev.ly only. 336.ily isn't changed.


HTH,
  Harm
