I purchased this today, I wanted to give you a heads up about an issue I just had that caused the editor to crash.
I was playing the Features level and I was in the spot explaining how AI goes into alarmed mode, with an AI with its back toward me. I shot it and it didn’t react right away so I pressed the stealth kill button. The animation started for the player but the AI had a delayed animation, after the player is done then the AI finished its animation (appearing to snap its own neck), the editor crashed right afterwards.
