Thank you!
Alright, thanks for the quick answer 
Had Same issue. CONFIRMED FIX for me was installing latest nivida video driver. Try and update your video driver and see if it helps you.
I have the latest Nvidia driver. Many people I spoke to said that the latest driver are causing this.
Same problem
Had this same happen to me today, everything was fine yesterday when I stopped gaming and went to bed. Had the latest Nvidia drivers from the time I started the game. Today, when I booted the game up again, the yellow dot was gone and I was kinda troubled. Started googling it, found this.
I ran around and noticed it wasn’t just some locks, it was every damn lock. I started loading older saves, and noticed it affected old saves also and locks I had picked before without any trouble. As a last option, I closed the game and started it again. And by Holy Father Godwin, everything was back to normal.
So no clue what causes it, but it affects the entire game, not just single locks and for me at least, just closing the game and starting it again fixed it.
For those who thought lockpicking was too hard before, I’ve discovered Hard Mode: 
The silver/golden dot does not appear in my reticle, making it practically impossible to unlock the chest.
I tried restarting the game, and the bug is persisting for now. I’m wondering if this would constitute grounds for a refund, or if I should just wait a year for the game to be patched and modded.
Just started happening to me too, trying to pick locks in Rattay,
Seems that this bug is still there. The last patch fixed it for me. Hm…
Same here. Had the game since launch day and this is the first time I’ve had this above bug. Reinstalled my copy of Windows today plus everything else. Might be related? Wasn’t happening yesterday…
It’s kinda making lockpicking rather hard.
Bug has been fixed for me. Thanks WH.
Strange, this was working again last night. Not sure if it was bug-fixed or if it just worked again, but if you lovely people fixed it, thank you.
The same thing is happening to me. I first noticed it while attempting to open a trunk in the enemy camp during the Nest of Vipers quest. Some people above mention that it’s fixed, however, I’m not sure if the issue fixed itself for them or was due to a patch. Any official word on whether this is being formally addressed by the developer?
Yeah just ran into this bug myself. Literally just played like 5 hours ago and there was no problem with it, and now the balls gone. In any case, I found that even with the ball gone, the lock itself doesnt move (when pressing D) until you found the sweet spot, then once you do, you just have to lockpick it like normal at that point.
same problem here - I’ll open a case
I have the same mistake, some advice?
Same here…Ball is gone…
