and a much less famous case, giving me an opportunity for beating my own drum:
two structures of the bacteriophage T4 short tail fibre in which the
N-terminal parts are disordered and it was not possible to model
crystallographic contacts along the c-axis:

Another famous case of a missing domain - the tyrosyl-tRNA
synthetase studied by Fersht and colleagues. See Brick, Bhat, &
Blow JMB 208:83 (1989). There is no connectivity (i.e. continuous
packing) along one of the crystallographic axes.
And another thing for you to try - contour at a lower level than the
usual one sigma.
