NPC raised by SetPos Z and slowfall is instantly reset to ground
In the original engine you can make a NPC stay in the air, at least by giving them the "Slowfall" effect and setting their Z position every frame. In openMW even with a 100pt Slowfall effect, the NPC was a milkshake, alternated between the ground and the Z position they were set to. In retrospect the issue might have been that the SlowFall effect did not apply fully.
