I just got the bug where I asked her to wait, came back from clearing a dungeon, and she won't follow me. After searching a bit, there's one option I haven't seen yet - is there a way to despawn, and then respawn her using console commands, and if so, would this fix the issue?

Ah NM. Fix - http://www.rpgwatch.com/forums/showthread.php?t=17883
And if stuck in broken Ore Grotto, go outside and console moveto player

Man, you are an angel, thanks muchly.
