Xesht Kill Crash

Crashes and Stutters have been way worse since the last update.
Worst of it hit me tonight when I fought 4th difficulty Xesht.
Already on a hugely unlucky dry spell in maps, putting in massive time, effort and resources to my maps and build, and getting next to no meaningful drops.
So I fought T4 Xesht, finally beat him, right as I beat him, I watch the 'Furtive Wraps' drop, and right as they drop my game crashes.
The crash caused the kill to not count as well.
So I lost the loot, lost the atlas points, and just to add insult to injury lost the breachstone I used to get there. Robbed.
I'm getting very demoralized with this game constantly crashing and stuttering.
Please fix these stutters and crashes
