I played a competitive game on PC. It all started well, but less than two minutes later, the game just hung and crashed. I was going to quickly restart, but when I entered I saw that I had already taken 50 pts and were given a temporary ban. It was not a problem with the Internet, but with the game itself. During the crash flew a small window with an inscription on the crash. Why should I return the points that were taken from me through no fault of mine?
