When playing with Marverni, I have too had very often that after a battle, not one unit routs, but still most units are unassigned. Not from mage commanders tough - usually only from normal commanders (this is mutu (= I feel like it) and could bee wrong also).

Also the "unassigned after moving to target provinse" happens a lot. I didn't notice the "dropping before moving" because I had long lines of commander moving units and all of them dropping along the way, so can't really distinguish.
