KitKat -

The EXACT same thing happened to me and I deleted the one off the handheld thinking it was just a ghost copy or something and it deleted ALL my info and started me over.

To fix this here are some steps which the lovely ladycfii helped me with when I spazzed at my lost data.

Go to preferences and pause the game. Exit the game and hotsync. This will put a very recent saved game back up on your computer. Delete the one running on the main memory. If you can load from your memory card just fine then woohoo!! If not, if it starts you over, never fret! Go to your archive or backup file in your Palm storage on your computer. You should see one that save VillageSaveGame.pdb. Double click on it and it should bring it up to automatically reload on your handheld. Make sure it's installing to your expansion card only which should be an option once the "install this file on next hotsync" program pops up. Hotsync. You should be back to golden now!!

Be warned though - my "expansion card" is internal so I had a bit different go at doing this. You should be okay. Once I did this it has not replicated itself again on my main memory. For whatever reason I guess this is happening to people!

Good luck!
