In the Norway level where you have to watch the perimeter while the agent(I forget his name) opens the gate I have encountered a super frustrating bug. Right after he waves at you from the window, he runs toward some stairs and gets stuck. He runs in place indefinitely. One time I actually left the game running for two hours and he was still running in place. Unless I use cheats and use NOCLIP, I have no way of getting past the fence(that's another problem, even after I enable the console AND cheats, they don't work). PLEASE help. Has anyone else had this problem. BTW, I have patched the game.

I've had similar problems on the jeep mission
The jeep just suddenly stops and I can't do anything.
Just start again (I mean the whole game)
Its a pain I know...but it works for me.
