Server bugfix and critical error corrected

I had an issue with some line of code in yesterdays update that would cause black screen when loading the game after logging in,

Thanks to the testers this was corrected pretty fast !

Bugfixes : 

- When quitting a battle while repeating, challenge doesn't get triggered again.

- No more black screens on Android,

- Gear stat previews before swapping is now shown properly.

Thanks again to my testers, lets make this a great idle game !!
