When the game crashes, crash report is automatically generated and submited to us. It will then prompt you to submit bug report with explanation. It is highly encouraged to do so and explain us how you got that bug. That would help us a lot to fix it.
In case when you encounter a bug, but the game did not crash, you can press Ctrl+Shift+Alt+E to force report submission. If you are playing on a touch-screen device without keyboard, you can alternatively press and hold all 4 corners of the game screen until report popup shows up.
