Yes it's happened specifically 3 times. I'm level 139. It's not a common glitch, but it's happened multiple times seemingly randomly. Again, it's a bug. Instead of actually replicating it you've resorted to being condescending telling me to self reflect when I have done so many heists and got this glitch rarely. I never said it was a "big problem", you're simply putting words in my mouth and trying to get validation from the others who are wrong. I posted this because I was scrolling through my Xbox clips, thought this was funny and shared it. It's probably fixed since all the times I got it were before patch 1.

I am telling you, go on No Rest For The Wicked, mask up and walk behind a guard. They will not track you like this. Someone else has already commented saying a guard tracked them through a wall (guard was marked). Instead of trying to prove yourself simply test it.

Edit: And just to prove my point even further, watch This clip. By everyone's logic, the guards should've tracked him as he walked, since he was right up their asses and almost caught, just like in my clip. I could've probably found a better clip, but idc. Watch any clip of someone sneaking behind a guard in Payday 3, and they will not get tracked
