First of all, this game is amazing! I've beaten the game once and now I'm going through the new game plus. I'd like to say awesome job to everyone who worked on it. Here is the issue: The assassinate action has ceased to exist. Here is the story: It started happening somewhere in the Set to Flight level and I didn't hardly notice because I was trying to avoid killing any guards. However, I've started the The Return level and I definitely cannot assassinate any enemies (I've tried this with multiple enemies). I am using the nightmare armor (one of my favorites) not the silence armor so I should be able to assassinate. Also, I've verified the integrity of my cache and that wasn't the problem. Here is a screenshot: As you can see, I'm standing in assassination range and the icon is not there. If I left click the non-lethal attack will be triggered instead. I apologize if I'm missing anything obvious. Let me know if there's more information I can get to help facilitate an answer. Thanks!
