看来这个问题已经存在很久了,暂时无法修复,唯一的方法就是不要加载快速存档,这是PM开发者去年的回复: If you manually load a save via the Load/Save menu, the cache is also rebuilt for some reason. This is a known issue. Thus, either wait until the navigation cache is being rebuilt in that case (this typically takes 6-8 minutes, but could be even more depending on your PC), or do not load saves manually.
