When I died in a Swamp Byway realm the game stalled when trying to respawn my character. The "respawning in 5 seconds" counter did not count down and remained for 5 minutes before I hit ESC and returned to the main menu and reloaded the game. My guess is that you need to add a "default" respite point in these Byway realms thus allowing the game to respawn the character.
The impact to game play is not major as the game engine is saving progress all the time and very little progress is lost as a consequence.
