Game can't load with new mods

[MensIuguolo]

So, apperantly EVERYTIME I add a new mod, I need to start everything over?
Why?!
In EU4 I easily added new mods to saved games, this really bums things, since now I really can only consider new mods in between campaigns

Something must be wrong with your game because I can add and remove mods just fine.
