Re.
Error 3420 - Object invalid or no longer set.Huh! This was rather nice, I must say. I had to Ctrl-Alt-Delete and use Task Manager to close Aurora, and then I actually had to reboot my computer to get rid of the above error message. But that worked fine.
Plus, when I started the game again, I discovered that I hadn't even wasted any time. Apparently, closing the game through the Task Manager still saved my progress. That
was nice.
Well, it wouldn't have been so nice if the error had still been there, I guess. Heh, heh. But no, everything was fine. I thought I'd lost my geology team, since I couldn't find them on Phobos. But they'd been teleported to Earth, apparently. And this time, I was able to abandon that 'colony' on Phobos with no trouble.
Altogether, this was a lot better result than I was expecting.
