I believe that many people have come across the problem of wanting paused characters "unpaused" in a different location.
Most often, this leads to needing to pause an active character (loosing all progress) and then unpausing and moving the desired character before being able to resume play with the "original" character.
A possible fix to this might be to have all paused characters sent to a "LIMBO" that allows them to be unpaused to any location that a player has a free open slot for a character.
ie: a character is paused on BT and replaced with a new one.
Several months later that player looses a noble on Dwi and rather than start a new one, decides that the paused noble from BT would do well as a replacement on Dwi.
Current mechanics require that the player must do a lot of pausing/unpausing/emigrating to accomplish this. Much time is lost for both characters (also reducing the fun for the player who is unable to play either for a period of time).
With a "LIMBO", this could be accomplished with no disruption of play for either character, allowing the player to continue with no interruption to their game.
