Okay, so a quick update.
I actually found out that %appdata and everything in it is hidden. I've now unhidden it. Yay.
So I found the save file, transferred it over. Double yay!
But that's where all the good stuff stops.
I've tried everything I can think of to get my laptops to talk to each other, and it's no go. No matter which of them I use to host, entering the IP address, as asked, just makes the game sit there doing nothing for three minutes until it prompts me to try again.
To be clear, the IP address that's wanted is the numerical IPV4 version, as I've connected to other people in the past just fine. This is what I've used, and it didn't work.
If there's some special sneaky command because we're both on the same IP already, it would be kind of nice if this were in the manual, because the manual gives the whole online connectivity thing about three or four lines and calls it good.
Really beginning to remember why this game frustrated me so much. So many hoops, so little kickback.
