So, I found a problem with Sydaily using her range attack.
When I use her for attacking few raiders, the explosion that always "reduced to atoms" everyone nearby just didn't happened. Like I saw Sydaily firing, (that little meter in front of her face) but nothing happened after.
Well no, something happened. The game doesn't want to run faster then on normal speed. I can
still pause the game but can't go faster. And also FPS dropped to 10-16.

After opening debug log, this message was spaming there:
