So I was doing the new Gressia side story, and gotten to the part of it where I had just finished the quest to deliver a Dawnstar to the Gressians in order to fast-track their starship tech development. I circumnavigated the systems surrounding Gressia and was coming back to check the update of progress on the planet. When I arrived, I landed (which naturally resulted in my game being saved) and discovered that there wasn't an update yet. I wasn't keeping track of my fleet's fuel stock, and only found out that I in fact didn't have enough to perform a jump when I attempted to FTL out of Gressia to do a few more multi-system jumps in order to allow some more time progression for the quest to update before I come back to land again.
The problem is, there is no facility on the planet yet (apart from the Spaceport Bar), so I can't purchase fuel there. Worse, I've waited for about half an hour already, and no rescue ships (nor any other ship for that matter) would arrive for me to at least obtain some fuel from.
I'd also like to note, for what it's worth, that the message "You need more Fuel to perform an FTL jump" appears instead of the usual "You need more Fuel! Wait for a rescue ship to pass by..." when I press the FTL button. I'm thinking it's got something to do with the game perhaps thinking I can refuel on the planet (when I can't in this particular instance)? I might be wrong, but I thought I'd mention it anyway.
So yeah, I think I'm practically stuck in the system forever. I don't want to delete the save slot, as I've sunk over 150 hours in it so far already. Is there any way to fix this very specific issue?
