it just gets tiring for me, the truth is: nobody ever really knew how the missions worked, it was a mystery.
we decompiled it, studied it for weeks, checked and double checked and triple checked to make sure everything in the functionality was the same, triple checked it again, and STILL people say it's different from the original because the dice don't roll the same numbers they did in 1995.
by all means, feel free to study the code, ask about it, question it where you want, i'm not infallible. but "UFOPaedia says" are my two least favourite words: frankly it's incorrect about a lot of things, and almost deliberately vague about others, i've given up using it as a credible source of information long ago, and it would take a lifetime to correct all the mistakes.
