I've found another issue with filler text.

On an semi-unrelated note, has anyone in the Imperial campaign had issues unlocking all upgrades? I reached level 16 on hard and cleared all other factions and events. The only factor I think it could be was after beating the Dark Throne (Necron elimination) it did not award me with an upgrade like other faction defeats do.
