In the previous UI, if you ticked the safeguard option, it would stay ticked even if you went beyond 17 stars or got a chance time.
Now it seems that whenever you hit a state where safeguard is unavailable (e.g. 17->18, chance time), the option is unchecked when you get back to a state where it would be applicable (e.g. 15->16, 16->17 without chance time).
Steps to reproduce:
- Star force starting at 15 stars.
- Enable safeguard.
- Get to 17->18 or more, and then back down to 15 or 16.
- The option will be disabled when it should still be enabled (as it was in the previous UI).
