Well I have approximately 200+ Mods all set up with the Fallout Mod Manager, Well I was going through all of them clicking on some ,seeing which ones were compatible etc. etc, Well at a certain point in time all mods not currently checked off if i check them they will turn my saves null, And I know its not mod incompatibility for I had it in working running condition with mods selected, and I unselected some of these mods and reselected the working ones again and it starts to make my saves Null, do I have to reinstall my game or reinstall mod manager? If anybody has run into this problem before help would be appreciated.
