There was no room for vandals and foolishness.
Keep in mind the vandals and thugs are out at night.
485 the whole of Sardinia was taken by the Vandals from Africa; but in 533 it was retaken by Justinian.

Lost to Rome by the invasion of the Vandals, who took Carthage in 439, the province was recovered by Belisarius a century later (533-34), and remained Roman till the Arab invasions of 648-69.
