Bug fix and saved data lost 😨

I fixed a bug.

• An internal error had been occurring when using Cluster Missile.

That's good, but another problem occurred. :(

Saved game data was lost 😫😫😫

I apologize for the inconvenience. 😭😭😭😭😭

(No problem to play now)

Why~~~?? I am using PlayerPrefs function of Unity for saving data, that shouldn't lost even if the app is updated.

I am currently investigating.
