I just realised that if you send your crew members on tasks and you transfer to another instance of the planet you are on, your crew completes the task while you are on the loading screen. I can confirm that this does work for Armstech however i haven't tried it with any other crew skills. While switching instance I had 12 lvl 37 weapons qued which take 3m 45s each and they were all completed as soon as the switch finished. Can someone confirm this with other crew skills?
