We are aware of an issue where some players unable to play The Tangled Vines or Gnome Improvement because the game freezes when trying to tap the "Play" button or "X" button on the event menu. We have narrowed down that this issue only affects players who have completed all chapter tasks currently available in the game. The freezing will not happen if players have tasks remaining. A full fix is expected to be released in an upcoming app update, version 1.22. In the meantime, we highly recommend that players refrain from completing all chapter tasks until they are finished with the event. Apologies for the inconvenience as we work to resolve this issue.
