Wow ! Thanks Beard ! For anyone who reads this post, the problem is definitevely the mod "Authentic Z". [WARNING] unsub/reset/resub is not enough to load the save, you have to launch PZ, "chose mods" from the corrompt load, click on (activate) "Authentic Z - current" and desactivate the other one "Authentic Z". It works very well, i'm happy ! Thank a lot and have a good game guys
