+1 to this report, i was about to report this myself, exactly what he says, hope you can fix it.When Increasing Attributes in Career Mode, you end up in a scenario where the amount of SP required is higher than the trainer gives you.
It says I need over 14k SP and the trainer gives me 9999.
For Ability Purchases, the level 3 abilities exceed 9999 SP in cost, plus the counter went down with every purchase I could get. I fixed this by going into attributes and exiting. The same applies to VC.
I was incorrect. The SP won't replenish in the ability purchase menu.
