Hi Everyone,
With the upcoming R136 update, the development team has uncovered a critical bug in the build for those who would still be playing on iOS 7. It appears that loading any Helpshift page would cause iOS 7 users to crash the game.
This issue is unfortunately unavoidable for R136, however it will be fixed in the following R137 build. In addition, upgrading the OS to a more recent version should prevent players from encountering this issue, as well.
Thank you for understanding.
