NHL points 25>26

Criminals. 

YOu know I buy a golf membership, and I have money on my tab it will carry over to the next year. 

EA, this is not hard maybe 50 lines of code.  

I asked Claude 

"

Give me the coding for a video game to transfer funds from one season to the NExt.

In this example NHL 25 takes money and you can buy EA points to buy player cards.

But I have 5000 coins left over and the new game is coming out. I want to show how easily it can be done to write to the code to transfer the funds to the new game"
