When I play the game, I see this message "koikatsu could not load shader KKUSS". Ive played Koikatsu some time ago and never such message appeared, but when Ive downloaded Koikatsu today, after in the first day of school, after first period was ended, such message begin to appear from time to time in left uppper corner of the screen. When I skipped to the next stage of the day - "Go home" stage so to speak, the message disspeared. Can anyone tell me is there a way to fix this, because last once already when I tried to ignore that message, the game crashed after some time.What can be the cause of that problem and how to fix it, so it wont appeared again at all?
