The following issues have been addressed in the hotfix:

• Players will no longer crash when playing multiplayer with other players who do not own The Last Roman Campaign.
• Battle lighting will no longer remain dark after the climate change events occur in The Last Roman Campaign.
• Flattened the terrain in Rome to fix buildings which appeared in offset sections on the battle map.
• More Separatist armies are now spawned during rebellions. This will only affect new playthroughs/save games.
• Langobards are now unable to join confederations in campaigns when the player owns Celts DLC. They are bloodthirsty barbarians who pity diplomats.
• The Ostrogoth Kingdom’s "Pro-Roman" objective can now be completed, as it's now possible to give diplomatic tribute to the Roman Expedition.
• Fixed an issue in the Multiplayer Campaign script of The Last Roman campaign, where the Roman Empire acted as if The Roman Expedition had separated before it had done so.
• "Maintenance Cost" will now be displayed for religious buildings in the Building Info panel in Grand Campaign modes.
• Belisarius will no longer be listed as the Emperor in the family tree during The Last Roman Campaign.
• Two of Theodora's missions in The Last Roman Campaign now use the correct art instead of the default mission scroll.
• Births will now show up as events again.
• Fixed some military (red) technologies having civil (green) icons in the tech tree, both in-game and in the Encyclopaedia.
• The Reinforcements trait will no longer display a huge number of "Turns remaining". The trait is awarded on completion of a mission.
• Increased the reward for "The More the Merrier!" objective in The Last Roman Campaign, when playing as the Vandalic Kingdom, from 1000 to 1500.
• The correct icon for the "Prosthetic Hand" ancillary is now displayed consistently.
• The Last Roman Campaign is no longer listed as "Belisarius" in the in-game purchasing menu.
• Unit stats will now only be displayed to one decimal place in the Encyclopaedia.
