Also, if this is not possible I would like my initial save file reset for the game I have just created.

For most mods, your best bet is to create the save with Custom Advanced Setup Screen. If this is not possible with the mod you're using, just let me know what the URL is for your game and I'll modify the save by hand to whatever difficulty settings you want.

Hi,

My game URL is 'http://multiplayerrobot.com/Game#16381'. This is actually my second attempt at fixing the issue. In this case, I uploaded the incorrect initial file so I think just resetting it so that I can upload a new one and play my first turn would work best. I emailed about this issue at about an hour ago so you can disregard that email.

I tried a test game with myself and another person plus two AIs and the game was created with the correct difficulty settings (humans had their difficulty set to the same as the AI), so it may have been just a fluke error.

Alright, I think I've got the game reset. However, resetting a game is a bit tricky and requires some manual work, so if something doesn't work right you may need to leave that game and start a new one.
