I realized that my mod has some problems because the save file is "dirty". If I start a new game there are no problems.

So: is possible to clean dirty file games?

No, not as far as I know. Some people are hoping the devs behind Wyre (or some other tool) may be able to create something to do this.

ok, thanks anyway for your help

well... really the problem isn't the savegame: the bug disappeare when I use the command "showracemenu" and I change race. But, if i exit the game and i return i need to change race again. So i need to reset my pg.
At what can be linked, definitely?
