Having the same issue... I can continue the main story, but I cannot complete the pre-chapter 1 Alderann quest to get Vector back from being a 'guest'. I've reset the mission at least 5 times now at different points to no avail. Hopefully I will have some luck with customer support.

Anyone suddenly having trouble with this space battle? I could easily do it a few days ago but now the escort ship just suicides 30 seconds before the end...
