Repost of my replies to another thread today in a more apropriate place :
My achievements and favor have gotten broken after pretty much every game update no matter which game type I play. This time it got stuck at -1375 (cost of the last favour item I bought, and the only one I have left) when I started playing a custom game.
What's new this time is it's stuck at -1375 and keeps resetting agfter every game. After a game is finished I check game.prefs and the negative points value has gone down, but the next game I play it goes back to -1375 at the start
Also, editing the game.prefs won't "stick" anymore, I can get it to work for one single player game then it reverts back to -1375.
[Update 1]
Been playing around some more with it trying to unstick. Oddly if I play a couple of custom games the negative favor in game.prefs will keep getting smaller by the amount of favor I earn, but the displayed in game favor doesn't go up.
In single player I can earn favor and the displayed number will go down, and I can play with game.prefs to get favor back, achievements and delete/add unlocked items but as soon as I play custom it reverts back to -1375 with no achievements and the one item I unlocked last, and will be like that for single player matches again.
I've tried deleting LastGame.DGReplay (My Documents\My Games\Gas Powered Games\Demigod\replays\[Profile Name]) since it seems to store details of your favor from the last game in there too but still doesn't un-stick my favor.
It's like there's a backup of my favor stored elsewhere now which will overwrite game.prefs and that's gotten broken to the point won't even update at the end of games anymore.
[Update 2]
Ok, completely new profiles that start with 150 favor in single player start with -1375 favor in multiplayer too, so it looks like it's something linked to my impulse log in that's broken. I can't find any more local files so I'm left wondering if there's something stored on the impulse servers now.
Can I ask if the SD guys if there's anything to do with favour stored on the impulse servers now? If so I think it's kinda died and left a horrible mess on my account. 
Hehe, just been reminded of the old TF2 quote in Demigod form... "Spy's sappin' mah favor!"
[Update 3]
Just checked my stats at http://pantheon.demigodthegame.com/games/player/11298/page/1 and it seems to have lost all the games I played between april 14-23, all it's got are the load of quick custom games I've fired up to figure out what's wrong with my favor and the couple of games I got in on the release day.
