3rd attempt at Alpha silo to launch nuke. 3rd crash.

My first attempt crashed when I was in the hallway on the way to the control room after I tore up the mainframes. My 2nd attempt crashed After I reached the control room and was on the way up to start the defense of the launch crew. My 3rd attempt crashed after I had just finished destroying the predator assault droid. I dont have it in me to try a 4th time, let alone at charlie or bravo sites and have the same experience. I took 3 days off of 76 between my 1st and 2/3rd attempts. I just might not come back after tonight.
