I finally figured it out. I just disabled every Mod and the Game AutoSaves with No Issues. It is someone's Mod that is corrupting the AutoSaves. IF YOU DO NOT KNOW WHAT YOU ARE DOING, DON'T MAKE A MOD. It's the Mods! SONY has Prevented Scripted Mods, Limiting it's Players. I signed a Petition Against Sony to Allow all Mods on the PS4, Scripted & Non-Scripted Mods Alike. Now I understand why Sony Limited it's Players to non-scripted Mods. If a Non-Scripted Mod could cause this much Damage what could a Scripted Mod do...Delete everything you worked so hard to obtain? I am beginning to TRUST these Mods Less & Less. I AM REALLY PISSED, THAT I HAVE TO START MY GAME OVER WITH NO MODS. This is because I have over 50 Mods & it is impossible to find out which one of my Mods is Causing the Problem with the game's AutoSave. I AM REALLY DISAPPOINTED!!!
Ça semble être un Mod corrompu.
