compressing full-bar rests

[N. Andrew Walsh]

Hi List,

I have a general question. Has compression of full-bar rests been somehow
disabled? I have the following score:

\version "2.21.1"

global= {
 \time 4/8
  }
%% (and whatever other settings I want)

oDAMusic =  \relative c'' {
    \key f \minor
    R2*12

    | %13
    r4 bes
}
\score {
\new Staff = "Staff_oboeDA" <<
      \global \oDAMusic
    >>
}

-------------------------
The 'R2*12' statement used to compress down into a multi-measure rest, but
now it's writing them all out. Is this a bug of some sort?

Thanks for the help,

A
