WHAT uniform?! lol

So, a short while ago, I killed some dude that I think was with the Imperial Legion and ever since, none of those guys will speak with me. All they ever say is, "Where's your uniform?"

What am I supposed to do with that???

In theory those things aren't connected. They should only be saying that if you're a member of the legion.

You sure you're not the member of the Legion yourself?

One surefire way to become a member by accident is talk with their faction leader with a certain topic open when it should not be, challenge him to a duel, then kill him in the Arena. Have you done that? Or perhaps joined without remembering.
