Issue with HISMC (LOD switched for all instances same time)

Greetings.
I’ve tried to implement HISMC. But it acts like ISMC.
LODs are switched for all instances at once.

For some reason can’t upload a video here.

Here’s video: https://i.gyazo.com/7b1b0ef4f79c42d55cf9ddd96b65de2d.mp4

It’s the same on 4.21 and 4.23.
