改造脚本中未应执行的指令却被执行了，求助!!

happinessizumi

是这样的，我在前天稍微改造了论坛上LBQ所发布的薄雾年代记存档脚本，
试图利用相同的思路改造一下脚本，不过我虽然看起来思路都正确，但是却出现了这样的问题：



本应该呈现这样的效果，选项选到哪里，那里的底图改变。然而有存档格的地方，会有一张图片贴在上面，然後会根据游戏中的[1]号开关产生变化



不过无论怎麽改，都还是会造成这样的效果。只要有一个存档存在，三个空格都会被贴上那一张图片，相当烦躁！！
但是怎麽想都不对啊，应该已经在判断式中不要让他执行了，他却还是执行了这一点让我非常苦恼。


这个问题已经困扰我两天了T_T 因为自己的程度不高，只能看懂不能编写，所以就去用别人的做改造了，不过还是有些地方看不太懂
但是这边在我脑筋打结的情况下还是出问题了
希望懂脚本的能稍微看一下是不是有什麽问题以及怎麽改善！！

（话说上面有一些我整理的注记，如果有发现错误的也希望可以指出来><谢谢了~~）

※ 下面这串脚本中Face_2是一个与Face_0,Face_1一样大的图片，不过他是完全透明的
