I was fighting a Dragon in winterhold with my companion Illia, and when the fight ended she just stood there wielding two frost spells, as if ready to attack something. I can't talk to her or anything, and if I try fast traveling she doesn't come with me. Please help! She's a really good companion while playing on very hard difficulty, and she's been tagging along with me since almost the beginning. It just wouldn't be right to face alduin without her.
