When entering Eastmarch camp I′m supposed to talk to Almar stone fist. This is just before going to fort Neugard. However, he attacked me as soon as he noticed me. Several times, can′t kill him. He just gets up after a beating.
Gladly there′s internet nowadays. I read you need Stormcloack armor equipped before going to the camp. So where′d I get stormcloack armor... Haven′t seen in shops. Had to snipe one of the camp guards, sleep 24 hours and go back to Almar stone fist and yay, he wanted to talk without fists this time. Quest worked and went smoothly since then.

There was no indication at all in game that I should have stormcloack armor equipped or anything. Needs some fixing.
