There are quite often KK flaws.
Some happen more than others. Here are some flaws:
- Screen turning black | This commonly happens when you scroll through your friends really fast. To fix it, close the window and re-open it.
- Friend request not going away | If this happens, try declining it. If that dosn't make it go away, then log out and log back in.
- Kart going without hitting the button | The quickest way to fix this is go to another area.
- Getting stuck in the parts trailer | If this happens, try hitting the undo button. If that dosn't work, close the window and re-open it.
- Everything you have on gets blacked out | I don't remember how to fix this, so just try closing the window and re-opening it.
- You're invisable | Try changing what you have on. If this doesn't work, go to a different area. If that doesn't work, log out and log back in
- Screen freezing while loading | Close the window and re-open it.
