EDIT: doh, meant Flames, not Fireball to be more specific, I CTD after running from Riverwood to the Whiterun gates. As soon as I enter, two NPCs start yappin about needing weapons or something, and to my right is an unlit brazier. I start to cast Flames on it, and I CTD. I also had a CTD when I was outside of Whiterun and casting Flames at thin air. That only happened once and I'm not able to replicate it. I casted Flames on the road near Riverwood against a wolf and I didn't CTD. I casted Flames on a giant near the farms outside of Whiterun and I didn't CTD. I spent a lot of time getting these mods together and jus wanted to play ;; Skyrim.esm Update.esm Dawnguard.esm HearthFires.esm ApachiiHair.esm CLARALUX - More and Brighter Lights.esm ClimatesOfTamriel.esm Evil Lair of Hydra.esm MagicDuel.esm SPIKE.esm WARZONES - Civil Unrest.esm Brawl Bugs CE.esp invinciblehawkfix.esp Unofficial Skyrim Patch.esp Unofficial Dawnguard Patch.esp Unofficial Hearthfire Patch.esp Better Dynamic Snow.esp Rainbows.esp Clanking Armor.esp IceBreaker's Improved Reverb-v0.02-Cleaned.esp Improved Combat Sounds v2.2.esp Rooster At Dawn v1.0.esp realrainCoT.esp ClimatesOfTamriel-Dawnguard-Patch.esp MintyLightningMod.esp Fantasy Music Overhaul Redone.esp Weapons and Armor fixes.esp Weapons and Armor fixes - Hacks.esp StaticMeshImprovementMod.esp Economics of Skyrim.esp Economics of Skyrim - Dawnguard.esp 83Willows_101BUGS_V4_HighRes.esp ArmorRatingTweak80.esp ArmorRatingTweak80_1000AR.esp AV1Dragon_Lords.esp BirdsHF.esp GuardsGuardThePlayer.esp Immersive Battles.esp Immersive Brigands.esp Immersive Dawnguard.esp Immersive Patrols.esp Immersive Travelers.esp Immersive Werewolves.esp Perks Unbound.esp Perks Unbound - Dawnguard.esp Radiant and Unique Potions Poisons and BOOZE.esp ShootingStars.esp SPTDiverseGuardsSkyrim.esp Destructible_bottles.esp Character Creation Overhaul.esp Footprints.esp WetandCold.esp SkyUI.esp iHUD.esp 1nivWICCloaksCRAFT.esp DwemerAutoBlade.esp Gatti12Jewelry.esp hothtrooper44_ArmorCompilation.esp Insanity's Dragonbane.esp KCEAssaultRifles.esp KCEBattleClaws.esp KCEScytheOfDeath.esp viciousdawnbreaker.esp DeadlyDragons.esp Run For Your Lives.esp When Vampires Attack.esp The Paarthurnax Dilemma.esp Acquisitive Soul Gems.esp armored-horses.esp BetterQuestObjectives.esp BlockSparkles.esp CCO - Oblivion Carry Weights.esp CCO - Permanent Birthsigns.esp FSS-No pause between lines.esp Guard Dialogue Overhaul.esp Hide_All_Helms_and_Hoods.esp Immersive Weapons.esp ImprovedScImpUniforms - Main.esp Increased Bounty & Guild Rewards.esp NonEssentialChilds.esp Proper Aiming.esp SkyTEST-RealisticAnimals&Predators.esp Thieves Guild Requirements.esp TwoRings.esp Uncle Sheo.esp VariousGuardReplacer.esp Waterbreathing Breathless Emerge.esp Unique Region Names.esp Open Cities Skyrim.esp OCS + Hearthfire Patch.esp dD - Realistic Ragdoll Force - Realistic.esp SkyrimSpeeds.esp ToL_Core_by_Brevi.esp Apocalypse - The Spell Package.esp Balanced_Magic.esp Balanced_Magic_Dawnguard.esp FlashStep.esp spelleraser.esp SSAPBWK.esp BFSEffects.esp DeadlySpellImpacts.esp FNISspells.esp ForgottenMagic.esp Realistic crime report radius.esp Duel - Combat Realism.esp ACE Realistic Fighting.esp Dual Wield Parrying_SKSE.esp The Dance of Death.esp ACE Speech.esp CCO - Dynamic Skill Progression.esp ACE Archery.esp ACE Armor.esp ACE Enchanting.esp ACE Magic.esp ACE Melee.esp ACE Smithing.esp ACE Synergy.esp Beards.esp numenume Hair.esp TeraHairWeightFix.esp navetsea female face preset.esp Amanda.esp Lyla.esp Michelle.esp Misha.esp CCO - Diverse Races And Genders.esp ethereal_elven_overhaul.esp changed syntaxes.esp getSnowy.esp WATER.esp Blacksmithforge water fix.esp RaceMenu.esp RaceMenuPlugin.esp Remodeled Armor - Vanilla Replacer.esp wtbs.esp Bashed Patch, 0.esp ASIS-Dependency.esp ASIS.esp I run Wrye Bash 1st, then I run FNIS, then I run ASIS choosing only "Automatic Perks" and "Automatic Spells".
