The errors might be subtle, but don't go unnoticed for someone who's obsessed with the game like me. Right now I remember three:
1. The Towel effect should slow you down, but it doesn't.
2. The fade to black when you go to sleep in Masada's Spaceship is gone.
3. In the credits, one of the blocks of text appears abruptly, rather than slowly fading in like they're supposed to.
