If you fill the pitchers with water and bag the plant and slowly acclimate over time, the pitchers can sometimes be kept alive and well. Even if you don't bag, filling the pitchers will prolong their life after shipping. Either way, it'll recover eventually if there are no other issues with it as it gets use to the conditions and settles in.
Another lesson to learn. I am a newbie and I want to fill cups but I'm afraid.Looks like they've solved it for you... if you ever get some nice pitchers on a rare plant just fill them all the way with water to preserve them until the plant starts making pitchers again.
