Patch v1.12 updated

· Fixed a bug that the game might crash when pressing Alt without saving any equipment combination

· Fixed bugs in boss and plot performances

· Added warning at the end of the first chapter so that there is less possibility that the player overwrites the protection file by ignoring the plot. (Which might further result in that the player delete all his/her save file)

` Fix the bug that event might be interrupted when hotkeys are pressed in high frequency.

Thanks to all friends who found bugs and made comments!
