Ha. Sorry, I should have explained. That was from a converted ck2 file. The ck3 game that I'm trying to export is named "Emperor Garrett VII 1444 05 10", where the converted Barcelona mod, from 1445, is from the ck2 game.
So I had a ck2 export, got ck 3 and played through, now I'm trying to port that game, save file named above, but it doesn't appear. The converter believes it has made the file - as shown by our ability to see it in the paths select screen.
However, in the actual /mod folder where my actual mods are, the converted ck3 game isn't there. The entries are either from the Steam workshop or my own beginner attempts at making a mod.
So - the issue is that the converter isn't exporting a mod file. Or any file. But it really believes that it is.
