Captain Valmir in front of Forelhost claims to be an officer from the player's supported civil war faction. If he is dressed as a Stormcloak, he wears the Stormcloak Officer Armor as he should. If he is dressed like an Imperial, he wears light Imperial armor. The thing is that high ranking members of the Imperial legion wear heavy Imperial armor. This includes the captain during the game's intro and all Legates.
This does not cause any issues during gameplay, but I still wanted to report it in case the USSEP team thinks this could have been a developer oversight or error.
