It seems sanctuary transitions have some issues with henchmen / animal empathy, etc. They can't follow or use the transitions, so it would be nice if they could either be added to the teleport when transitioning, or adding a command that allows you to jump your companions/summons/animal empathy to your current location to circumvent the issue.
Sanctuary Transitions: The "black screen delayed transition for atmospheric purposes" such as those found in scrags or the very end of alhoon.
