Hmm thats weird... same thing happened between the initial disable sathanas mission and when the Big C tries to destroy it... it somehow had all 4 main beams active... tore the Big C to shreads! I couldn't destroy more then 1 beam before the Big C was dead. Oro... well good luck! I think its corruption in pilot files... check to see if you can see your squad logo in pilots room... if its just like...

it probably means your pilot file isa bit corrupt... sorry! If that's not an indicator... thats what happened on mine when my pilot file was a bit corrupted.
