Your welcome, and if your characters are stuck in Last Cave, I'm not sure on how to get them out. I would clone them in your regular FH.
Also, FH + does not have: South Pole, Last Cave, Atlantis, Fluorite plains or Ficho. So if your character is in any of those maps, and your home is set in somewhere like Sky Rim in regular FH, press reset home, it will take you to bonfire.
