That is encouraging

So by backing out would I still get the quest triggers...?
The items in your inventory - are you "stuck" with them there and can't sell them etc...? Apart from the weight etc that might not be a bad thing as long as the quest could still trigger..? That last item that you have noted which will not "go away" can't you use the tilde key and use the console commands to get rid of it..?

Thanks also for posting about the NPC's - I was worried about killing them, but it has happened, and future quest issues. But as I got no messages as such I figured it might be ok. It was just that some of them were named characters, but hostile, rather than just being "bandits".
If you pick up a "named" item can you deposit that item in your house for safe keeping or is it stuck in your inventory until the quest gets triggered..?
So long as you don't grab the quest booty, or come across the actual quest objective you should be fine.
Any items that are stuck in your inventory don't actually count against your weight limit (apparently) like they did in other games.
In my case, I avoided console clipping because I thought I might eventually trigger the quest..didn't happen though in this guy's lifetime

As an aside, I have been to a couple of dungeons on more than one occasion, and the last time was as the result of a quest...now, I can't be absolutely sure after so long in-game, but I had the feeling that the actual later quest component of the dungeons weren't there when I went through them earlier...as in there was an entrance through walls that I didn't recall, and same for the quest objective.
Possibly it could be that many people wouldn't pick that up unless they did lots of time in game, and did lots of the quest lines, or it could be that I'm imagining things...but I really had that feeling on a couple of occasions. If that is the case, then Beth has found a very good workaround for multi-use dungeons and quest layouts.
