Why so glum?

I would rather remove its effects than the trait itself. Then you won't have to worry about the triggers affecting it.

    Condition Trait ForcedMarching > 0
          and Trait Temperament < 3

This here is the reason then. I'm not sure how they get low or high temperament, but forced marching is guaranteed to lead to grumpyness if it is low. Maybe you should, you know, not push them so hard. It's only natural for them to resent their lot in life if you keep wearing them out.

Edit: Not to mention the host of other negative stuff that comes from it. It's a hint.
