If you disconnect or crash at the end of the fractal, by the time you get back online it will be over and you miss getting credit. This has happened to me one too many times. I'm done.
Yeah, this has also happened to me one too many times. But I know the problem is on my side so I really can't complain. Things happen sir. Shake it off and move on.
Are you running the game off of wifi internet?
While there could be more fail safes built in, not sure it's the games fault when you have an unstable internet connection (playing via wifi for example).
