I was about to do another Stormcloak quest. Its the one to liberate Falkreath Hold or something, but when I go to the Stormcloak camp, Galmar or Gamlar Stone Fist randomly attacks me, no other stormcloak men attack me. And of course I cant kill him because he is important I guess

Sorry, I didnt know what section to post this in

Reload to a previous save. Sometimes NPC's just go wild and start attacking me or each other.

Ya, I have tried all that. I have just been using him as a sparring partner now anyways, working on some skills, lol. It will probably be patched evetually
