Ok , so i just bought new PC installed Skyrim on it and what's heppening is that when like for example in one tower are 3 bandits who defending it when i get closer and one of them attacked me immediately other 2 came down and start fighting me so , i end up killed 3 vs 1 ..they are coming from all the way top of the tower to the bottom and start attacking me but it shouldn't be like that..in my other characters i just go kill them 1 by 1 and it's ok...so , if someone know what causing it or how can i fix it i will be thankful to hear please .
