I've tried to create an example, but when I try to isolate the problem, it goes away. It's apparently an interaction between multiple rules, and I can't seem to come up with minimal set.

I'm banging my head against the wall, getting different problems and seeing behavior that doesn't make sense based on my experience with CLOUD mode.
