I pre ordered Sots2 on Impulse, but dont seem to have access to the Liir/Morrigi immersion packs that it was supposed to come with. In game I can see them on the faction list, but I cant select any, they are all greyed out. When I pre-ordered, I was sent an email with some kind of Key code, along with the bill of sale and all that. Ive tried that code on Impulse and Steam and neither works. So is this something just missing or have I done something wrong? Ive been given no other code via email.....
