Every time you restart or reload the game your last saved NC amount is subtracted with the total amount of NC's spend buying suit enhancements.
I presume this is supposed to be a subtraction of the total amount f NC's collected in the game so far with the total amount used to purchase. Or something similar.
Can anybody verify that they have the same issue. Lets see how quick EA is with a response.
==> I already send this to EA Support: The incident number is: 110403-011042
How did I get there:
- Started a new profile and new game.
- When I had 500 NC I quit the game.
- After restart NC still at 500.
- Purchased a 100 NC upgrade and played until next checkpoint.
- Quit again.
- After restart NC was at 400 ( 500 - 100 for the suit enhancement)
- Played further until I had enough to buy a 600 NC upgrade.
- Played further until I had 1040 points and hit checkpoint.
- Quit Game.
- After Restart I had 340 NC ( -700 = 100 for first + 600 from second upgrade).
If you quit the session, but stay in the game, your points are not touched. Only if you quit the game back to windows and start again the [Mis]-calculation happens.
This explains why there are so many different amounts reported. Also if you buy enhancements when they become available (Have enough NC) you will probably not notice it much. If you are a saver (for the 16000 NC price) once you quit and restart you will never get there again.
As this is known since the demo, I don't understand you did not find it earlier. It took me less than a day to figure this out, and most of that time was playing the game to get the NC's required for testing.
