Adding my report here- edited to add that I'm a subscriber, in case that matters
My grade 11 crew skills missions have gone missing, grade 11 is no longer available in the drop down menu. In addition, the two of my three crew skills, Bioanalysis and Diplomacy, are listed at 600/600 when they should be 700/700. Only my Biochem is still listed as 700/700. When I first click the Bio and Diplo buttons, exactly two grade 11 missions will come up, but listed as either grade 1 or grade 10 on the drop down menu. Also, some of the grade 11 Diplomacy missions show the dark side symbol when completing, even though I am locked in as light side. After reading some other reports, I tried going to the trainer so see if the option to buy was available but it is not there for me.
