Game client crash rate increasing exponentially for no apparent reason?

  1. What do you want to achieve? Keep it simple and clear!
    My game (Truck Chaos)'s crash rate has increased exponentially, from barely 2% to almost 50% today. I want to figure out the reason, since I have not changed the code or added more features that could have affected performance.

  2. What solutions have you tried so far?

I have published multiple updates which use optimization techniques from the documentation, but to no avail, even though my stats (memory wise) seem good.
