I currently have a British Dasha mounted on the temporary premium Lightning. She is specialized for the Black Swan, but I want to keep her on the Jervis. Since the Jervis will soon not be premium, is there any way to get the captain retraining done while it is still premium (so I don't have to deal with skills not working during retraining). I can't figure out how to start the retraining process on a premium. How do I do this?
