Viking Predator broke some features

During all the match against VIking as FT i heard sound of beheading (fast fatality for ft).
1)Viking was spaming he’s axe secondary attack, then he just stop and we killed him. I think predator player got a crash or freeze, because he doesnt leave but stand without moves.
2)After we killed him, ai started to die with a delays and weird VFX (like eyes and glasses in the air, when head was destroyed).
3)Also, after pred was killed, my hero lost ability to sprint.
4)After match ended, my endflow cinematic started with a delay in 2-3 seconds

I think it was me, after almost 1 month without playing and it breaks in the first game, there were only two alive and I was about to kill the third, a shame
