I cannot load any game that was played by a single player. Each time I try to do so I get a message that says "Not enough players".
For the sake of solving solo puzzles, this would be nice to have fixed. For example, there are some example logs in this thread: http://forum.dominionstrategy.com/index.php?topic=17016.0
Example logs: 1505394, 1511253
As a workaround, you can load those games by creating a table, setting the min number of players to 1, then loading the game via the options.
Thanks, I got this to work.
