Actors ignore vertical axis when following player
1)Cast levitate on self and on actor following you.
Following actor will run to the point right below you on the ground, and will never levitate.
However, if you force an actor to attack you instead of following, he will run after you in all three dimensions (maybe that was fixed in #1335?)

Tested vanilla now, and you are right (it was kinda strange for me, but I guess I was confused by "smart" script-assisted companions from some mod who could follow a levitating player). But original point of this report was more about inconsistency between following and attacking behavior.
Anyway, it could be a nice improvement over vanilla, before or after 1.0.
