Within their Grasp - Breachstone dropped by Breachlord bugged

The Atlas Node "Within their Grasp" is not working currently. Its supposed to have each breachlord drop a breachstone with 5% chance. I did 20 Maps now with each 15 Breaches, each with at least one Breachlord (~300 Breachlords) and did not get a single Breachstone dropped.

It might be due to the changes with how the splinters drop at the end of the Breach. Or something else because i didnt see any solution for old posts regarding this.

I am barely even dropping splinters tbh, breach has been really weird since they changed it.
