Near the stables in Whiterun I noticed that an npc was stuck in the ground with 2 others on each of his sides. They are all 3 the exact same npc and not moving anywhere. After doing a ton of quests and passing them again I noticed that there were 4 of them this time. On top of that I can't kil them as they are essential. Here's a pic I took to show ya. I forgot his name though.

Known issue with Louis Letrush.

I just did his related quest. He has not cloned on me yet, but I am waiting for it to happen.

Yes this is a known issue. Make up some back story about creepy quadruplets and ignore him. If you are on PC, you can use the console to disable them. Not sure if they come back or not.

ya I'm on pc and didn't know it was a known bug. I tried doing a search but didn't find anything lol.

Thanks for the info.
