Can you note down:
SP at the begining of your game.
SP you spent on abilities.
SP you then have at the end of the game.
I have a feeling that either the XP modifier is being applied to costs, OR you are getting charged double.
Cheers.
Right now i had 12
I spent 12
Now i have -12
And i can't play a game because i'm short PP :/
i saw that today. was quite strange. i mean, in the launcher i saw that it said you were out of SP and thought that it was pretty weird.
