no, you do not. i noticed the glitch on level 4 or 5 and came here to see if anyone else had this problem. upon finding out that i was not alone, and of the cache clear, i immediately cleared it which solved the problem. just don;t download the update until you have collected all intel.
it is worth noting - if you don't already know - the fallen eagle achievement glitches too. that can be fixed using the usb/profile move method
