Game crashes whenever I tap objectives, or if I complete an objective by accident (since I have no idea what they are anymore) when I click the pop up, it crashes.
It didn't always do that and it doesn't happen on new games though I assume it's only a matter of time.
I've googled around and this seems to be a major android issue but just letting you know it is now an iOS issue as well.
I'm having the exact same issue. Everything else in the game is fine but as soon as I press the challenges tab it crashes instantly. I'm hoping there doing another update for the bugs.
