I am not a vampire. I do not have a bounty. I had already completed all Forsworn Quests.

I needed money so I went back to Cancelmo's Lab to get metal to smelt and craft dwarven weapons.
When I entered Cancelmos lab the quest Hard Answers got restarted. All guards attack me on sight. But I had already completed that quest!

And I still have Thieves Guild quests incomplete that require me to go to Markarath.

This totally renders the game unplayable!

Does anyone know how to break this cycle?

Thanks!

Of course, I am on a PS3.... *sigh*

Well the last time I aggro'd a town full of guards, I ran out of town, out of aggro ranged and then used the wait key and waited three full days before trying to go back in. Don't know if that will help or not, worth a try.

Hahahaha same thing happened to me not even an hour ago! The quest restarting, I mean. One of Daedrics must really despise you to have the guards attack you and not me for it

Sadly, this really renders the game unplayable for me.

I bought the house, I just completed buying all the furnishings, I am Thane of the city, and as soon as I fast-travel into the city, every guard attacks me.

This is ridiculous! I have sneak 100, with boots that enhance sneak. I can creep up on dragons, and I can't sneak there without having every guard attack me. This is just nuts!

Try what Leydenne said. That usually works. You have, of course, just tried yielding right? Just so you know, if you enter a town with your weapon sheathed you have to pull it out and then sheath it again to get the guards to allow you to yield.

Yes, yes I did.
And this opens up an endless loop where I can't bribe or persuade or exert Thane influence.
No matter what response I give, it says I am a murderer and I will pay for my crimes.

This is so buggy it really frustrates me. A lot.


Edit:
And if I sheathe the weapon, the same guard attacks or arrests me again.
And more come, and do the same.
Last night I had a group of 5 guards trying to arrest me at the same time.
As soon as I closed dialogue with one (circle button) a new one cried: "Halt!".

*sigh*
