But I'm almost certain I've used Dynamic Weather before (some time back) and not had this issue, so... it could be some kind of incompatibility, I suppose.
https://picasaweb.google.com/113520644781376104771/Fallout3Album1?authkey=Gv1sRgCKXp0oG8yOT3qQE&feat=directlink is the anomaly I'm talking about, by the way. Between shots 1 and 2, and between 3 and 4, there's only one step, and a couple of seconds. Otherwise, identical in every way. Or, they should be.
Is this a known issue? Just point the way, if so. Must admit, I'm out of the loop, somewhat, with FO3. Been spending too much time with Oblivion, once again.
So, sorry if it's a dumb question (another?) or whatever.
