Thank you. After some depressing real world stuff, I'm actually able to enjoy some straightforward space-trucking again. Even went all the long 626,311 ls way down to Celsius Estate, Anduliga in my Type-7 to pick up some fireworks, and tried to leave it on Supercruise Assist while I got ready to go out. I came back just in time to find I'd been interdicted, shields down, hull at 62%. I charged up and high-tailed it out, and decided to remain in the cockpit this time, which was a good decision because I got interdicted again as I approached the outpost.
As many would have already realised, the trip was all for nought, as their landing pads discriminate against my type (as in "7", see what I did there?

), which I obviously didn't bother to check first. But I wasn't even mad. I just turned around, headed for Eranin to stock up on some rare Pearl Whiskey and other potable high demand goods to fill my 256T cargo bay, then hopped the 5 jumps to Reorte to deliver. Will head back later today to help spread some more festive cheer to Davies High.
