In this scenario the Bulgaria route and Hungary route are really different, just like two scenario in one map.

I know this glitch, too. And also, if you start an easy mode test in Map Editor, quit, then load the campaign file, it will also become easy mode But there are some differences from the Dark Age giltch in AOE2, you need to quit from game and start from the savefile. So @Mhmd_FVC Can we use these glitch in speedrun?
