#save_all ⇒ Object

we don’t do this. there is no proper way to update all given characters one must not rely on a character properties after the doc has been manipulated use Character#reload to get the latest from the doc object to the character and Character#reload! to reload the doc from the database and reload the character then def reload_character_objects()

@just_reloaded = []
@character_objects.each do |character|
  unless @just_reloaded.include?(character)
    @just_reloaded << character
    character.reload
  end
