Bug? "Feature"?

[Bhruic]

I'd noticed it before, but recently I got conclusive proof that something is up with the +rank giving V&Vs. For example, the "expert defender", or "expert attacker". My King was a decent 4 stars. He had, however, "expert attacker", giving him +2 on attack. When I moved him into a hostile province (to attack, obviously), he did show the correct 6 stars, and the troops with him went from 2 valour to 3 valour (correctly). However, when the battle screen started, and I hit F1, the King was back to 4 star. The units under his command were back to 2 valour.

So I guess my question is, is this a bug? Or is it taken into consideration "behind the scenes" like moral effects are?

I noticed this too. "Expert defender" doesn`t seem to work at all. I also don`t have the impression that it`s just not shown. Sometimes you can tell the difference in valour from seeing their effect in battle.

Maybe it only has effect on units as they are doing the appropiate actions, i.e. defending/attacking...?
