Im sorry i took me so long, i wasn’t working on my project for i while, but i have found what was the problem and it is crazy.
So the actual thing in the BP, that caused the problem was changing the scale of destructible after event begin play!
I wasn’t expecting that! I tried everything and then by accident i found that when when im changing world scale 3d to a new one the problem occurs, and when i am not changing it everything is ok. I was able to replicate it in clean project so i will submit it as a bug.
