The naval rank-up process for major factions is bugged to the point where it's not playable--I'm choosing to stop until it's fixed.
Last night, I did my first 3 naval rank-up missions for the empire. I made it to Master rank.
Today after trading, I went to complete my rank 4 mission. I complete it successfully and return to the station that assigned it (Gould Port in Tamar). I complete the mission in the bulletin board. I look to my right panel. I see that my Empire rank has been reset to "NONE." WHAT?
Ok, that's a pain. So I take a deep breath and start re-doing the missions.
I take a mission to rank me up to "outsider" again. I complete it, come back, turn it in, and achieve the rank. I do the same with rank 2, serf, and achieve that rank. Things are starting to look good.
Then I take an assassination mission for "Master" rank. I kill the target, return to the station, complete the mission...and I do not rank up. I'm stuck at Serf. I quit and reload the game. Still no rank-up.
At this point I should be one rank away from Baron. Now I'm stuck at serf, despite the huge number of missions and naval promotion missions I've completed.
