I encountered a rather strange bug where a scripted NPC fall death (on one of the early missions), ended up falling into the pavement.

He actually fell correctly the first time, but I ended up having to reload, and when I went near him again this time, he fell and died in a very unfortunate manner.
I consider this an extremely minor bug, and actually maybe worth just leaving in as long it isn't breaking something else somewhere else as it's pretty hilarious.
