Q. "Unable to find game." (MAC)

Q. Game crashed on setup. ".....data structure / index doesn’t exist..." (MAC)
A. It can happen if the option / saves are corrupted. Try to backup and remove all files in ~/Library/Application Support/com.SissyMaker.SissyMaker and try again; unfortunately there’s no way to recover the corrupted saves at the moment.
