Greetings Demigod Fans,
Long ago we've reported a bug to GPG about Favor Points resetting on us. This got worse in release as now they dip into Negative numbers for no reason. Worry not, this is not part of the game design. In fact, the entire game's player recording system is completely broken so all of your achievements, purchased achievement items, and favor will often get deleted. Well how do you resolve this issue on your own? Very simple, so simple you'd think I'm joking.
The Resolution
Turn off your game. If the game is running, this will not work.
Go to My Documents/My Games/Gas Powered Games/Demigod
Locate the Game.prefs file.
Open the Game.prefs file in a Notepad.
Fixing Favor Points
Go to Edit, Find.
Search for "Points =" without the quotes.
On the "Points =" line, alter your favor. The line should look like this:
Points = -2280,
Either just delete the negative, or edit it to whatever number you desire to afford the achievements you already bought, or really want.
Then Save and close file.
Being Able to Use the New Favor and Erase Old Favor.
Once you edit the Game.prefs file, go ahead and start the game.
Go to Multplayer - LAN.
Host a quick LAN game solo with an AI and begin.
Check your Favor, it should be the number you recorded. Then go to Menu, and End Game. (Not Exit to Windows)
Do not exit the game. Likely, each time you exit Demigod it will mess up your Favor. Just jump right into Multiplayer.
Afterwards, you can go online and play with the new Favor. Pantheon included.
