Temple of Kopec Vaal Ruins are bugged

Hello,

Firstly, I know it's the end of the league and this is very unlikely to be fixed or even worth looking at but...

So, I like to farm up vaal ruins in the campaign (yes, i enjoy the campaign a lot). But when it comes to farming vaal crystals in the temple of Kopec in act 3; 80% of the time they do not activate once all the mobs are dead.

I have farmed on multiple characters and in many maps, found great methods and locations, Kopec would be amazing as it's mostly always near the entrance and on the 1st floor.

But it really only ever works 1 in 20ish runs. Kinda frustrating.



And yes, I have made sure I killed everything and am aware that the annoying casters might float away or even the worhippers could be part of it. I have tried killing the entire floor. They are bugged more often than not.
