I remember when I installed op2 from the cd and with just the offical patches it would never crash, and it was mostly like that with the 1.3.3 update as well
but now after I reformatted my computer, I downloaded the 1.3.4 version and now op2 crashes all the time, for simple things like trying to see what the mission objectives are, or somtimes just for random reasions
so if you have a fix for this, please set it so I can download it, if not, im just letting you know the problem
