Running on PC. Got ~200 hrs in and ran into this bug while I was in SI. 'All' non-rigged animations are super-super slow (spell effects, doors, waterfalls, etc.). Character animations, weather, and water surface animations are fine. Seems to be associated with savegames as I've gone back to previous and not having the problem. Anyone seen this?

It sounds like the A-Bomb bug which slows all animations down. You can fix the savegame via http://tesnexus.com/downloads/file.php?id=22368

And, if you don't use Wrye Bash, OAF: http://www.tesnexus.com/downloads/file.php?id=5127

Yep. That fixed it. Thanks to all. :hugs:
