I am at Vandenberg in the Command Centre, at one of the control units Carla Brown tells you to go to, to restore back up power to their bot defense system, I entered the code 5868 and received 100 skill points, I accidentally clicked on it again and noticed it gave me another 100 skill points.. My friend is currently playing the same level on his computer and it did the same thing.

So I kept clicking on it until I had about 14 000 skill points
Then I upgraded a bunch of my skills, then I quicksaved (the last time I did a proper save was back in hells kitchen just after Hong Kong), then I clicked on it again until I had another 10 000 skill points.. And now every time I try to save the game crashes, this isn't happening to my friends game, but he didn't go for as many skill points as me.

Is there any way to fix this?

Thanks.
