So I've been playing Skyrim since it's release and I just found today a new bug I'd never encountered before. First I traveled from Riverwood to Whitrun and when I arrived I saw 5 guards just walking in a line as close to eachother as possible. Now at first I was like "Oh wow lol that's a neat little bug." but then when I go to exit Dragonreach after informing the Jarl that I've killed the dragon I see his 3 kids comming in the front doors from outside in a perfect triangle formation. Since these happenings I now see people walking to places they never have before. Lars Battle-Born who in most of my saves never even wants to leave his house now actually leaves the city on a regular basis and the Jarl's kids are almost always running about town, again something they never did before. My question is, is this normal behavior? I've never seen this before in the countless hours I've played Skyrim and it's really bothering me that my game may be bugged this badly. I'm also afraid that if this is a bug I'll end up having other npc's bug out and possibly cause issues with my game.
