Oh, wow. Okay, they're not floating; the game is trying to help me by showing that they're on a different elevation. This could be a lot more clear if some degree of transparency was applied, instead of making it entirely invisible.
Also, I'm not sure if it's even possible to get Lae'zel up where my main character is, now? I can't click to tell her to move up there, because the game is trying to be helpful and not rendering that ground at all...
