Does This Usually Happen?

I reached the credit limit today, and i just mucked around in matchmaking because i can not get any credits but when i finish a game and it shows me how many credits i got.

It takes away what i have earned, say for instance i got 1598 Cr it takes it away from my balance.

does this usually happen?

i am guessing not to be too complicated, they take away those credits

maybe it is to show how well you did, reach’s ranking system really can’t do that but still

Completely normal, it tries to add those cR on and then just removes them.
