It seems that the story manager is getting hung up on this one locale for the Dawnguard quest "Ancient Technology": it's repeatedly sending me to ruins I've visited before. I haven't gone to many other dwarven ruins at all yet, and there are also plenty of bandit locales... but it's repeatedly sent me to Kagrenzel (which dumps out into Stony Creek Cave). It's set to prefer completely unvisited locales in its location alias too.

So is there some console command to give it a swift kick?

It doesn't need kicking. Well, it does, but it won't help you!

What other conditions are applicable for that quest? A particular type of BOSS? A particular type of REWARD? Anything other than a bandit lair?

(I'll have my CK in operation shortly, I'll check the Quest and the SM Event Node to see what - if anything - I can see. Is almost always a conditions which looks random, but isn't though)
