Mortal Kombat X PC: Weird Fatality Bug. Skip to

Hello TH-cam. This is a small video where I show myself practicing with Raiden during several fights. The main part I wanted to highlight is the very end of the video. Apparently, when i do a fatality, very rarely will it not happen. Surely enough, it does take longer to do this "secret fatality". What do you guys think? Has this happened to you before?
