A thought just occurred to me - you made some of the sound effects louder, and I think the same should have applied for the old songs you'll hear in some levels (Panzerlied in "Cannibal" and others, Alten Kameraden in "Die Spies", and what was the other Wehrmacht song
).
And I've found another problem - that topless chick you added in "Hotel" doesn't show up, and it's ridiculous to see the guard kissing thin air.
