I get this error when there are problems with the bars accross different voices
or staffs. There might be one bar where the total duration exceeds those in the
other voices.

Hi Nick,
You use two voices in your example.
In the second bar you only print the b-natural once.
But in the second voice you print the b-natural twice:
% Bass voice
down = \relative c' {
c4 c | % 1
b! b! | % 2
d d | % 3
}
Change it to
% Bass voice
down = \relative c' {
c4 c |
