I finally could not take Nazeem anymore so I put a frenzy poison dipped pick axe in him which resulted in his demise at the hands of Whiterun guards. At the same time, the guards came after me for my assault. I took refuge in the Companions' house, and many Companions came to my aid against the guards. In matter of seconds, a bunch of Stormcloak guards and lot of my pals in the Companions lay dead, including the old lady who swept up the place. I fled town and came back a bit later and was given the option to pay my bounty, which I did.
However, when I went to lay down to sleep in Breezehome I received the message "you cannot rest while guards are pursuing you." I thought, "What guards? I paid my bounty." In fact, all the guards in Whiterun were peaceful to me. I left town and tried fast traveling. Same message: "you cannot rest while guards are pursuing you."
Now, no matter where I go I keep getting this message. And no one seems to be pursuing me. I am not allowed to sleep nor fast travel. Has anyone heard of this? Did I break my game? Damn you, Nazeem!
