On the bar scene around minute 13-14 when William Lee (Daniel Craig) notices the centipede necklace, he lifts his glasses over his eyebrows with his left hand and hold it like that, on the follow up scene his glasses are correctly in place and his left hand not visible. The next scene when the man across from him touch William's leg, he is still holding the glasses above his eyebrows and then correctly puts it back in place.
As Daniel Craig as William Lee, prepare the chess board with Drew Starkey as Eugene Allerton the chess setup keeps switching from being incorrectly set up to being correctly being set up. An example is where Daniel Craig places his queen where the knight should go and then the next shot it's placed correctly. Then again a few seconds later the board is setup incorrectly again.
