Nevermind - Figured it out.
I've gotten the mission to return an item to the BOS general and when I do a HUGE horde of mutants attack, ranging from Deathclaws, Centaurs, Aliens and fire geckos. If I take out my weapon to attack the mutants the BOS attack me, but If I don't they kill the mutants. Is this a bug ? I also get a dialouge option from someone saying "Is there news" Or something to that effect. I can choose to say "No news" or "I need fuel to fly out of here" if I choose the fuel option the game crashes...Another bug ?
Another question - I got the mission to find the scouts and report back, found them trapped in the cave with the Enclave outside, they attack me but I ran to the exit and then the game crashed. Another bug ?
