Update:
1. Device: Galaxy Nexus Android 4.1.1
2. Games version: 1.0.5.5
3. A description of the problem, and what you were doing when the problem occurred
The goal "Capybara Casting" has expired a long time ago (a month maybe) and the Finish button has shown up but I can't press it. As in the attached screenshot, the Finish button label is blurred. Looks like there is something wrong with the button itself.
What was I doing when the problem occurred? Nothing. The goal was impossible to complete without using gems to begin with. Since I didn't want to waste gems to complete a goal, I just let it expire.
I have tried the following without successfully fixing the issue:
1. Restarted Zoo Story 2
2. Rebooted the phone
3. Reinstalled Zoo Story 2
4. Reinstalled Android OS
Please help!
