In Player Career Mode

I play my player only.

So when I am getting substitued I get the menu wiith the option what I want to do for the rest of the game. I am used to simulate the end of the game.

And simulating the rest of the game is highly unrealistic. 

-Lately I got substitued less than 10 minutes before end of game, I was leading 2-0 with Manchester United in Premier League and when I checked the result in the game plan, I won 5-2 ! Like 5 goals in less than 10 minutes !!!

-Even worse, I was playing with RC Lens in 2nd French league against PSG in Cup Final, and I managed to get my team win 3-0 at 85' when I got substitued and when I checked the result after in the game plan : I lost 4-3 !!! That's more than completely unlikely and I did not win the Cup due to this bug !!!!

So in conclusion for me this bug is also a No-Go for the Career Mode !

How often does the bug occur? Very Often  (75%)
Steps: How can we find the bug ourselves? Control the player only. Manage an unlikely result (like winning against the odd, for instance with a 2nd division against a 1st division team. Get substituted very close to the final whistle (around 85'). Simulate the End game.
What happens when the bug occurs? When back to the main menu. Go to game plan to check the result of the previous game. More often than not, your good result will be turned, like a 2-0 win a couple minutes before the final whistle gets turned into a 3-2 loss. Or if you are winning 2-0 with th odds, you can see your game getting 5 more goals in less than 10 minutes and ending with 5-2 win.
What should be happening instead? Last minute goals when simulating should be less likely and more than one shoudl be extremely rare.
