Darvin Mission Bug

Trying to finish Darvin's companion mission. Get to a certain point where your helping the Gryffin and the second time you do it glitches. The scene goes black like a cut scene is about to happen or the next part. An it stays pitch black. It corrupted my auto save file, I hear noises in the Forrest and the Gryffin but it is still pitch black. I check to see if there was any issues with the files on steam. An no issues there. EA please fix this.
