There are currently two known issue in version 5.8 of the game that may occur after updating.

Known Issues:

• Tapping tappies within the environment (such as pets, club houses, or hidden spots) may not display the collection animation during your first launch of the game after updating to 5.8. Your items will still be awarded despite the animations not playing. Rebooting your game after encountering this issue should resolve the issue. In rare occurrences this may also happen during long play sessions. Rebooting your game should again resolve the issue. 
• During tasks and projects where the star progress bar is present at the top of the screen, tapping on the colored outlined items may not show the progress bar filling up during your first launch of the game after updating to 5.8. Your progress will still be awarded despite the animations not playing and the bar not filling. Rebooting your game after encountering this issue should resolve the issue. In rare occurrences this may also happen during long play sessions. Rebooting your game should again resolve the issue. 

Solution:

Rebooting your game after encountering either issue should make the animations return and your balances update, if you collected an item.
