Uhm I'm having a small problem. I bought 10 Mistrals and equipped all of them equally with Trade Command Software Mk1, 2 and 3. Also navigation Command Mk1 and Fighter Command Mk 1 and 2 amongst others.
All of them are new. I couldn't start up with EST from scratch sicne I didn't have the tradking rank for it. So I thought I'd put all my Mistrals at ST duties in Home of Light, so they gain that rank for me; it worked well, before I could tell the 8th the order to ST I already ws Trader, therefore I set the 8th, 9th and 10th to EST which they did. But the ones that alreadys tarted trading as Secotr Traders had the option in grey. I made them stop, even drop their cargo, but nothing happened. DO I need to "fire" the pilot somehow? How do I do that? Is there any other solution to this?
Thanks a lot.
[EDIT] Okay! Problem solved, just had to read a bit further and I'd have encountered the solution

Just have to redock the former ST into a station and then give the order to start the EST again.
