Thx you guys, i don't have fix my problems. But its a mod who add a new donjon, some mob or textures missings probably cause the crash. I fix my problem by the quest command "Player.sqs <id>" + "setstage <id>" because i needed to enter in this donjon for a quest, so i have completed this by the console commande... So the donjon still alway crash my games. edit: i have adjust my settings and deleted my pluging.txt + order.txt, after this steps i have a new message from crash fix but now it's "meshes" who cause the crash not the "textures". i think my old order.txt was bad. but the mod still crash only for that donjon The mod who crash its Undeath by antioch (Great necromancer mod) with his donjon, The Arkay temple. EDIT 2: Nifhealer or NifScann cant do the job, nothing is corrupt in the report. i rly thinking its the mod & some textures changer who cause the crash.
