I'll take a turn
Game Crashed so I'll give you what I have done so far instead.
Mission: Multistorey Mayhem / Firefighter
Link: Here Ya Go!
I encountered a massive glitch which caused my car to freeze against a taxi in Mulitstorey Mayhem, took me about 10 seconds to get going again. Eventually completed in 100 seconds
