Background information: I treat my xbox with great care so I'm fairly sure that these problems are due to the game and not the console itself.

For some reason, when I enter Whiterun, random people ( not including gaurds) attack me. The guards actually run away in fear, rather than trying to kill me or my attacker. I have no bounty there and I don't wear any armor that might make them attack me because of brotherhood quests or whatnot (murders that might make someone want to attack me) for faction reasons. the other one is i did a few Companion Quests, but any time i see Farkas, he follows me until im in conversation range and talks to me automatically. No matter where I go, he just follows and talks. I have a follower already and I tried to kill him, but he just gets over it and keeps coming back. I apologize if either of these glitches have mentioned before in previous threads, but I didn't check too much so yeah. Sorry in advance if that's the case. Otherwise, if you also have these problems just post below and we might find some help. if you do have a solution though, please help me. Thanks!
