Guys, how often is your game crashing?
I mean: you are just driving, nothing unusual, but suddenly the game crash.
Today, it crashes 2 times in less than one hour... Fortunately I was running on the unmodified races so I lost nothing, but 1 minute of my life.... I remember it crashes also one time during the last arines challenge, while I was on modified... Very frustrating in that case because I have also lost my lap time.

Anyway the game needs to not crash at all during normal playing (like RR3 always do, at least on my device). RR3 also show a message if you are playing with too many apps in the background). 

I have sometimes a few apps opened in the background, but I'm not sure if this is the cause of crashing.
My device is iPhone 6, iOS 9

Please anyone reply with your experiences
