PianoStaff context not staying alive

[Shane Brandes]

Greetings all,

This week I resumed a massive project that was on hold due to hardware
constraints. I am typesetting a concerto and I have placed the piano
part in a PianoStaff so that using \context { \RemoveEmptyStaffContext
} in the layout block does not remove the piano part throughout the
score, though it removes all the other unpopulated staffs. This works
until the very last system where the piano part simply disappears. Is
there a easy workaround for this or am I possibly fouling something
up?
