Battlevoid: Harbinger BUG REPORTING

This time I finished my run I had a solid connection and my score still wasn't uploaded =(

Proof I was connected to Google Play (there's an "unable to connect" message if the connection is bad): http://i.imgur.com/nbBzW2k.png

Proof of end game scoring: http://i.imgur.com/glcaNAW.png

Proof it saved the score: http://i.imgur.com/r9cVeg4.png

Is there some sort of cap placed on scores to prevent hacked scores? Are we playing "closest to 9999 without going over"?

Thanks!
