Howdy Derek! Didn't even notice it was you when I posted my first reply!

I haven't run into this, nor have I heard of anyone having this problem (which doesn't mean it's not happening to others). I'm curious if closing the session, clearing disk cache (if you're using it), and re-opening makes the problem go away for a while. I suspect it will.

Since fades are not rendered to disk it makes one think that the cache is somehow getting corrupted. Perhaps a RAM issue? I'd be curious if behavior changes when disk cache is toggled the other way from where you have it now? Do buffer sizes make a difference? Can you run the session from a different drive with different results? Don't really know, but there's a few things to look at...

Good luck, and let us know what you find out!
