So, I replayed the prologue to get the pacifist achievement and headed over to the first mission. I made it to the vent as usual but didn't receive ghost XP. Tried it a few more times, no dice.
I could have sworn I had received the ghost XP at that exact spot before so I loaded up an old save I happened to keep from the same level. Do everything the exact same way and yup, there's my ghost XP. What gives?
