Actually I joined the game after new patch with season of the Viper and I see that I alredy have used some reward points in my reward book - in the tab ,,Letho os Gulet". first two Ores, then icon of Trophy wich needs 3 reward points and 1st story node on the right. In addition, in Quests tab I have already played 2 matches of Season of the Viper.
Problem is, that I didn´t play any match yet and neither spent any points in reward book. Someone hacked me or its just bug ?
