Interesting glitch happened to me today.
From time to time I like to wolf out in the middle of crowded cities and proceed to tear the ever loving shit out of the place which allows me to get some feedings in to boost my werewolf skill progress. My choice of target this time was post Imperial victory Windhelm. I went were wolf and proceeded to kill various citizens and guards of the city. Here's where things get weird.
The Imperial guards not only didn't attack me, they actually helped me rack up a higher kill cound by shooting anyone who registered as hostile, even the children.
Much fun to be had with all that.
