Nevermind. just uninstall the add-on and reinstall it and he'll be alive and well just as before.
Once I shot him myself, I thought he was a white leg. The hit didn't kill him and he didn't become hostile. It is very easy to be confused when he sneaks just behind the white leg. At a disance wih a sniper rifle it is very difficult to see.
Strange thing is normally, if you kill one of the "important" characers in the add-on you trigger the quest "chaos in zion" and fail all the normal ones.
What is your acive quest actually (in honest hearts) ?
I just played through it agian. This time there was a white leg on this ridge. I zoomed in to make sure it wasn't, Chalk.
Then I entered vats and took 3 shots at him. What I didn't realize, when I entered vats, it wasn't the white leg anymore. Chalk must have killed him and then stood where he was.
Luckily, this time I missed Chalk and he wasn't hostile.
So I'm gonna be alright, I don't Like Utah as much as teh Mojave though ...
But despite having 3 kids, I think Waking cloud is hot. I've had a thing for bald chicks ever since Babylon 5 ...
