Changing who is on an instructor pay plan now only affects the instructors you actually added or removed.
- Instructors who stay on a plan keep the pay you set for their specific classes when you add someone else to it.
- An instructor you move to a new plan is removed from their old plan straight away, and a plan with no instructors left now shows as empty.
- Saving changes to the old plan's pay rules no longer moves that instructor back onto it.
