I was just trying to play the safe cracking minigame, and the sliders that tell indicate when the number is most accurate did not move. they twitched near the bottom once but never slid up and down to indicate when to click. 

i just wanted to make this known, since it had never done this for me before. 

I've been having this problem for a week.  Works OK once, then it stalls again the next time I try..... 

Kinda glad to see im not the only one hving this problem.. i've actually resulted to keep away from the safe cracking minigame because of it 'glitching'
