Whatever I try to do, several doctors are assigned, as they have minor passion (which I automatically assign as priority 3), even when going through the work types settings.
When making the doctor role not available for automatic assigning (clicking the light bulb), it does no automatic assigning at all anymore, for any jobs.

Secondly, after a pawn has had bed rest as a patient, it will no longer be assigned anything, even when using the update now button, sometimes this is fixed after restarting the game.
