@Grabbles Yes, you will have to re-hire her after an import. (She will stay following/waiting after a normal load though of course). This is due to one of the limitations of the FCS where you cannot have a trader be a member of your squad. After thinking about this more I've made some tweaks to cost (Down from 50,000 to 30,000) and stats to account for those who need to import in a way that I think mitigates the downsides.

if she doesn't join your squad then she'll most likely disappear every time you import, correct?
