- **Comment**:
Actually, you don’t even need \autoChange to reproduce the bug:
~~~~
<<
\new Staff {
c'''16[ c''' c''' \change Staff = "z" c']
}
\new Staff = "z" { s4\p }
>>
~~~~
Not only is the beam messed up, the Stem is misaligned as well:
~~~~
<<
\new Staff {
c'''8[ \change Staff = "z" c']
}
\new Staff = "z" { s4\p }
~~~~
This produces a whole lot of errors and warnings:
~~~
programming error: Grob direction requested while calculation in progress.
warning: no viable initial configuration found: may not find good beam slope
programming error: No viable beam quanting found. Using unquanted y value.
warning: weird stem size, check for narrow beams
warning: Not drawing a box with negative dimension
~~~
(Reproduced with 2.21.0)

Here is a bizarre little bug I came across today: for some reason, an invisible
rest on a different Staff seems to affect the kneed beamed stems on a
PianoStaff when using \autochange. See:

:::TeX
\version "2.19.28"
A = { c'''16[ c''' c''' c] }
B = { s4\p }
