So I've got a new character, still level 1, just finding his way around Whiterun.

I go into the Drunken Huntsman only to find Elrinidir to be immediately hostile to me!

What's going on? My guy's not been around long enough to upset anyone, and he's been chatting to the guards quite happily.

Anybody know what causes this, or, better still, how to resolve it?

I'm on PC so if there's a console command to change his disposition that'll be fine.....

Not sure if it'll work but you can try selecting him, inputting "0005A1A4", and after that "disable" him and then "enable" him.

Or you can try to use "setrelationshiprank x", where x is number from 4 to -4. Try and go with 1 (friend), 2 (confidant) or 3 (ally) and maybe again "disable" and "enable" to reset him.
