Started a new game after a recent hiatus, Heimskr just stands around in Whiterun, never moves his arms or preaches. It's kind of an immersion breaker since I know he is supposed to. I don't have any mods installed that have anything to do with him, either. Anyone else seeing this, or just me? Is there a way to force his script to run?

Never had that problem in the 10 or so characters played.

sounds like a turn for the better, if you ask me.. tired of hearing his horrible voice in the background "....FOR YOUR VERY LIIIIIIVES!"

Haha, well put He's a real PITA.

Oh c'mon, you guys know you love Heimskr.

This is the second time I've seen this actually. I wish there was a way to debug it. Creating a new game fixed it though.

I noticed myself that (running latest version 1.4.27.0.4) Heimskr is not always there.
Sometimes he's just missing...
He's usually around (often he's in the bar) but he's no longer always preaching at his spot.
It's quite noticeable.

That is interesting, as I can say I've never seen him do anything else or go inside the Bannered Mare. I was actually looking at him and his scripts/scenes in the CK (not that I know what I'm doing) and as far as I can tell, he is only supposed to either 1. sleep in his house and 2. go to his marker and preach all day until a certain event happens in the game, but I am not at that point yet. This was pretty much almost a brand new save with a level 8 character. I'd never been to Whiterun previously, so I'm not sure what I could have done to cause any sort of corruption.

THen I played the game with my first character, I never heard him preaching. I guess its just a rare bug, but I can′t complain about missing him.

Same here, my first Skyrim character he did the same thing. I used to always wonder why there were posts on various forums/sites saying how annoying he was and wanting to kill him. I thought he was just another priest chillin by a shrine. My brother actually told me he normally rants ALL DAY LONG, and it was at that point I knew I had some sort of bugged save. Many characters later, I never saw it happen again, until now.

I've noticed this on my character as well, now he just stands there with his arms crossed, but you can still talk with him. If it is a bug, it is the best bug ever.
