Ok this I think I found a glitch or something as I dont have that many mods on my game and when the game starts and the wagons go down the path a little bit a elk runs in between my wagon and hadvar or whatver his name is and then a wolf half the time intervenes and gets attacked by hadvar and that kind of ruins the rest of the escape and wonder if this is a glitch or something or is this something that happens regardless of mods?

Are you using Helgen Reborn? That mod changes navmeshes in the area and shouldn't be activated until after you've completed "Unbound".
