Firstly, not an exploit. FDev have not hesitated to say something is an exploit when it is. When someone complained that the passenger runs out of Rhea had been nerfed, instead of saying "Oh, silly player, served you right for exploiting!" they simply said, "Missions will shift in frequency and payout with system state. That system is no longer in a boom state, so this is expected."a) using an exploit (mode switching for missions)
b) literally NOT playing the game for 40 minutes while AFK in supercruise.
Second, you go right ahead and try AFK'ing for the trip. I kept getting chain-interdictions every time I made the run.
By chain interdiction, I mean as soon as I beat one, the VERY NEXT MOMENT the second one started. Three in a chain, and it happened three times between start of the run and arrival. I switched to a corvette because I got fed up and started fighting them with guns instead of maneuvers.
Saying it's AFKing and an exploit would put Hutton Orbital in the same category, and I'm pretty sure it's established that it's not.
