Game Mechanics: Not maintaining z axis height with lev / dmf / bard song

[ElanoraBryght]

Since the patch this morning I am not maintaining z axis height with lev / dmf / bard song.

I've tested with Bard (Song of Travel), Shaman (Pegasus cloak), cleric (DMF), and Druid (levitation). None of them were encumbered. All tests in 1st person pov while looking up at the sky. All lost height on z axis at an unusual rate.
