Blood on the Ice will now allow you to complete the quest after the Imperials have taken over Windhelm. The guard acting as a CSI will switch properly to an Imperial as needed. In 'Blood on the Ice' (MS11), the player's chest in Hjerim would not enable unless Wuunferth was arrested for the crime.

The blood trails that you should note on it will lead to a big chest beside the wall. Open it to find the journal of a certain someone calling himself the Butcher and a pile of flyers warning of this murderer. The blood trails that you should note on it will lead to a big chest beside the wall. Open it to find the journal of a certain someone calling himself the Butcher and a pile of flyers warning of this murderer. There are a few ways. Break into Hjerim, which is the house in the furthest left corner from where you enter Windhelm. Go to the grave area (ahead and left from the pub) and talk to the guard.

So this quest was supposed to be fixed in the recent update, however i still cant start it, i have left windhelm and re-entered numerous times, is there anything im doing wrong??
Do you have to leave/enter through front gate or will fast travelling to the city/palace be enough?
Do you have to enter over differant days, or can you just keep leaving/entering all in one night?
I'm guessing you have to enter the city at night after the 4 times for there to be a group of people at the graveyard, but do you have to wait for a little bit or do they spawn there (does it take time for the people to walk to the graveyard?)
Also, i keep getting dialogue from the people in windhelm that goes like 'first my wife now my daughters' and other dialogue that suggests the quest has started, but its not on my list at all.
