"Xesht's Madness" atlas passive "Headhunter" bug.

"Xesht's Madness"
Catalysts dropped from Rare Breach Monsters in your Maps have 10% chance to be a full stack
Rare Breach Monsters in your Maps have the Soul Eater Modifier.

I have a HH and I can't get a stack of soul eater, even though the rare mob upstats says it has soul eater. In the game headhunter works strangely, sometimes mobs stop hitting you on the map and some of them don't even want to appear, and there may be a rare mob that needs to be killed to close the map.

Is there any chance for a fix for Soul Eater?
