I bought the Legendary Edition of Skyrim a while back and decided to start a new character. The first problem I ran into was that the carts in the opening liked to wobble on the road, almost toppling over. Then, after exiting the character creation screen, the headsman was off his mark, causing him to not execute the Stormcloak (or myself when I used the "kill" command on him.) after restarting, he was on his mark and the game normally (though the horse somehow got hurt before the title had a chance to fade in.) until I entered Alvor's house. some peice of furnishing was constantly rattling like it was stuck on something. Then when I noticed many of the animals kept teleporting up a few feet at random intervals, sometimes killing themselves this way. The waters liked to flicker at times, and in Moss Mother Cavern, it would act like they were swimming at random ticks, making navigating the cave a chore. Also, in Fort Greymoor's dungeon, opening cell door would cause loose object several feet away to fly across the room. Opening chests would have a simalur effect on nearby items, too. Breezehome and the Bannered Mare were two other places with the rattling problem, with some things being thrown with the slightest touch. Then there were more scripting issues. Mirmulnir's body wouldn't burn up after death (maybe I wasn't the Dragonborn that time, heh.) and after another new char., Alvor's wife would get stuck in the stairs, thus preventing early progress in the main questline.

I tried capturing a few of these glitches with FRAPS, but in the 30 seconds I record, the game acts normally. I ended up filming the bugs with a camera at the screen instead. Crude but it worked. I have the Unoffical patch installed, but turning it off didn't seem to fix anything.

Specs: i5 3350p 3.10 GHz quad core

EVGA GTX 650Ti

For the physics, turn on V-Sync

Turned V-Sync on; physics are running as usual and Alvor's scene is working properly. However I still can't get Mirmulnir to give me his soul.

Are you using all the unofficial patches?

Are you using any other mods? post your mod load order if yes.

List of add-on's in order:

Dawnguard, Dragonborn, Hearthfire, Official Hi-res textures, Majora's Mask, Windfall Island, Ezio's ACB and ACR robes, Barenzia Stone markers, Left hand rings, Glowing unread books, Followers can Relax, Unoffical Skyrim Patch, Bear musician, Moonpath to Elsewyr, Bandits Yeild fix, and Fall of the Space Core.

I also had one with Nigel Thornberry until his spawning in Riverwood and killing everyone ruined the novelty. Turned off SkyUI, too, once I suspected the external loader needed may have caused the problems.

I should also note that Mirmulnir died properly before on an earlier character, who later ran into a dragon that did not.

Well there you go, you are not running BOSS to sort your mods.

Also install "all" the Unofficial Patches.
