After I left a fort (Cracked Tusk Keep, to be specific), I ended up with the falling dust particle effect following me wherever I go. I see it outside, inside, everywhere. Here's a screenshot: http://steamcommunity.com/id/bVork/screenshot/651004031697986853

Is there any way to make this go away, short of reloading an older save? Setting iMaxDesired to 0 under [Particles] in SkyrimPrefs.ini does make it disappear, but that obviously takes every other particle effect with it too!

I'm using the 1.4 beta patch, if that matters.

I've seen this bug and it just goes away after a while and it's not a new bug with the beta patch.

Try sixchange twice.

But why miss an excellent opportunity for role playing a popular http://en.wikipedia.org/wiki/Pig-Pen?

You can think of it as "the dust of ancient civilizations".
