Theolitius and sixpackdaddy, I think you are correct, it looks like a problem with a UI component for crew (in logs there is WARNING: Scale9Grid for resource=15 has negative height -0.300000, which might indicate that some weird values are being used and the component flops).
@Aslain it might be the case that You can't reproduce it because of different screen size or resolution.
Using smaller ui-size mods (vertically - lower height - fewer rows in carousel or compact carousel f.e.) solves the problem - crew is visible.
