Under Disengaging (emphasis mine):
“A model in a unit that was engaged prior to being placed as a result of its unit’s Normal Movement must also forfeit its Combat Action that activation unless it is placed within the melee range of any models that were previously engaging it.”
Under Unit Charges:
“Remember that a model in a unit that was engaged prior to being placed as a result of its unit charging must also forfeit its Combat Action that activation unless it is placed within the melee range of all models that were previously engaging it”
Which is intended?
