Game work fine on Mobile Preview and in Standalone.

I have successfully installed and launched the “MobileTemple” and “StrategyGame” on my iPad.

UE4 installation is the 4.0.2 origin version with no modifications and no self-compilation.

When on my project I break many links in a Blueprint class, the game launch fine. Breaking this 3 flows and the game run on iPad :

I don’t understand why the project run fine in Mobile Preview, and why it crash on device ?

The complete log is included.
