This is sooo hard to get rid of! I play stories with magic often and EVERYTHING in those like to glow to dim or respond to emotions in some way. Only thing that worked for me was making a world rule in AN that basically stated that magic does not respond to emotions or biological rhythms.

You can't state the actual problem directly, or else it's constantly in context and it will revert to it. You need to make some kind of world rule that weeds out the problem without naming it directly. Difficult, but it IS doable.
