Icicles from shattering enemies aren't getting culled.

I have pretty weak 1060 GPU, but it runs pretty fine, I almost have stable 60 fps until i start shattering enemies. Every pack of 30 enemies creates enormous amount of ice cubes, which also respect physics, and it leads to massive FPS drops down to 10. Worst part of it that I have dynamic culling turned on, but it has no effect for these icicles, and I have to wait ten seconds each time for them to vanish.
Could you please let us remove them, or at least make them disappear by dynamic culling.
