Levitation energy cost reduction over snowy ground only works for a few turns after area transitions
When levitating, after moving to a different screen in the ice queen area, the "You easily glide over the deep snow..." message is displayed for two turns (three when entering the first screen from the wilderness map). For these turns, the character does not suffer the normal energy cost penalty for moving over snowy ground. After these turns, the energy cost penalty is the same as if the character were not levitating. This is weird. Either the energy cost penalty should always be removed when levitating, or there should be some explanation for why it stops working.
