A few comments:

The file is still open until the game is closed, so they should exit the game and THEN preserve the log file.

The folder that the log is in could have a different name. For the Big Fish Games version, it's Virtual Villagers - The Lost Children.

Finally, we can and will look at the logs as time permits, but we don't promise an answer for every situation. We will most likely only analyze logs that look suspiciously like a bug, so please provide some information about what you saw in your game that prompted you to post the log in the first place.
