Have you been having issues with the Augustus campaign? I think so did I for some years now. The main issue I had is basically the goals of the campaign get sucked out. When i would start a new roman campaign or any that is in Augustus, once the loading screen ended it would pop me immediately onto the campaign. The DLC intro cut scene never shows up and were you click the missions, all the factions missions are gone. The campaign is still playable but extremely boring without the faction related missions. Thus far it is only imperator augustus that has been doing this.

Yes, all DLCs and all campaigns are fully supported.
