Hi, I installed some mods, but on this playthrough Mirmulnir won't give up his soul so I cannot learn unrelenting force and start the dragonborn quest.

Here are the mods I have in this order:

Skyrim.esm

Dawnguard.esm

Dragonborn.esm

Hearthfires.esm

Update.esm

SPIKE.esm

ClimatesOfTamriel.esm

unofficial skyrim patch.esp

Improved Dragon Shouts.esp

Improved shouts Dawnguard.esp

Improved Dragon Shouts Dragonborn.esp

Improved Master Spells.esp

Improved Runes.esp

Improved Expert Spells.esp

Improved Casting.esp

Improved Cloaks.esp

Improved Destruction Perks.esp

hothtrooper44_ArmorCompiloation.esp

Immersive Weapons.esp

Skyrim Immersive Creatures.esp

Skyrim Immersive Creatures - DLC...esp

Alternate Start - Live Another Life.esp

ClimatesOfTamriel-Dungeons-hardcoe.esp

ClimatesOf
Tamriel-Interiors-Warm.esp

ClimatesOfTamriel-Nights-Level2.esp

Bashed Patch, 0.esp

All of this is from installing immersive armors, immersive weapons, immersive creatures, diamnized UNP, climates of tamriel, improved destrcution magic, live another life and the unofficial patch.

Help please?

Aha! You're missing the http://skyrim.nexusmods.com/mods/31083, http://skyrim.nexusmods.com/mods/23491 and http://skyrim.nexusmods.com/mods/25127.

It's the missing Unofficial Dragonborn Patch (UDBP) that's causing the issue. This happens if you have the main USKP and Dragonborn, but not the UDBP.
