Sometimes it will fix itself
It seems to have fixed itself without any action on my part

Never paid a credit. Oh well.
Meantime, I'm working hard on getting allied with everyone currently in power at Jameson's. There was one glorious day where a neighboring system was in famine and I could take multiple delivery runs at once, but that has apparently ended and now it's pick up 2-3 shipments and do a tour. So far, I have visited some unexpectedly weird places...
And I've become mildly obsessed with the day-glo brightness of NPC ships... pretty sure this has come in with PP 2.0, although I have lost track of who is orange. They make me feel kind of drab and dull. Maybe I should get on and pledge to someone just to get started. (Probably go with AD because that has the biggest discord community by some margin, and have been issuing weekly PP instructions for quite a long time. I appreciate that level of organisation.)
Anyway, getting close, and although I'm 99% sure these minor factions will rotate out in weeks-months, worst case that's 4 more allies in the bubble.
It remains useful that I spent a while back in 2022 or 23 working my way down the list of largest minor factions, and it is surprising where I can drop into and find at least 1 ally with good contracts available. Still miss EDDB's complete listing by system presence... Inara seems to have the top 20 but not much more. May just have to guess a bit - although again, if I pick a power to pledge to, it will restrict my space a LOT and I'll end up working my way through it.
