I hope this has not already been reported, although given its nature I think it likely. However given its nature I will post about it to be certain. I apologize for not reading the entire previous 75 pages of bugs to be sure.
When I enter any battle against an enemy's vassal I get a wall of read text that takes up most of the screen. After about 20 seconds of this it dis-appears, but no more text appears on the left hand side, eg. Casualty and damage information.
It appears in all scenes I have experienced thus far (I've yet to fight any sieges), against all factions. I haven't tested it against bandits and the such, so I cant say if it is only an issue with faction affiliated forces.
Do you require a savegame or any more information? Please personal message me if that is the case.
