Alright guys. There is a play dead code, but I just deleted it about 20 minutes ago from my DB because I wanted to work on it. But they arnt using a play dead code, thats the back fire of an "in correct knifing" mostly accures when they are trying to run and u decide to knife them, or if a major lagg runs by the room as you decide to knife. Btw found the code:

#Play dead
0x0027244c 0x03E00008

This is not what they were using, because this has happened to my friends that are non hackers many times when ive knifed them in glitch rooms. But you wanted it so there it is.
