Ok, so outside whiterun, right by the stables is a man called Louis Letrush.
The weird thing is he's riding an invisible horse and is also waist deep in the ground. To make things even more strange, he's surrounded by 3-4 clones of himself, all clustered around him.Speaking to one of the Louis' will result in them all speaking back in a creepy, unified way, and their mouths all seem to be bugged as their teeth goes through their cheeks when they speak.

As if this wasn't strange enough, as I was leaving Yngol Barrow, I was attacked by a blood dragon, which I promptly slayed. After this, I heard "I've never seen such a thing!" I turned around and who should I see but another Louis Letrush! I followed him as he ran around Skyrim, and he ended up at the Whiterun stables, where he ran to join his fellow Louis Letrush's and is currently standing where I presume he will remain for the rest of the game.
This glitch is, while strange, still very hilarious! I'd like to know if anyone else is encountering any similar glitches with Louis.
Also, I"m very scared that by the time I'm done with this character, all of skyrim will be filled with a horde of Louis'.

Oh yes, I have this glitch as well

I solved the problem though... I made it my personal mission to get rid of them all. I even got the money for the bounties I'll be collecting.

I'm experiencing something similar. Except he isn't riding a horse. He's just standing there next to a single clone of himself. His clone half way in the ground like he's sinking in quicksand. (minor spoilers ahead) And oddly, while randomly exploring in the mountains near Winterhold I came across him speaking to a mercenary who said "Raven sends her regards, Letrush" and killed him. Yet when I get back to Whiterun, he and his clone are still standing there in the same spot.

yes most people have that, also that thug killing happnened twice to me, its like agent smith!

Louis Letrush is becoming self-aware! Skynet is Louis Letrush!!
We're all gonna die!!!!

I have the exact same problem,it started out as 2 versions of Louis Letrush..and the other day a third one appeared lol Quite funny =) I think i figured out what causes it aswell.

Theres a quest in Riften that involves him and a certain horse named Frost. Anyways,when the quest is over and done with there is meant to be a little event that plays out in the wilderness surrounding Riften,involving him and an Orc thug.

However,if you somehow miss this minor event i think it glitches and causes the multiple version of Louis Letrush to appear. Im thinking this because a couple of days after i did that quest..and first discovered the bug in front of the stables,i randomly encountered this event playing out in the wilderness just outside of whiterun,miles away from Riften. Im assuming that maybe the game tries to fast travel him to your location so you can see the event..and he gets stuck in the geometry along the way lol Causing a bunch of clones to pop up until the event finally plays =)

I could be wrong of course,but according to the wiki the event in question is meant to be played out in the wilderness outside of Riften shortly after you complete his quest,not miles and miles away just outside of Whiterun lol.
