Characters appeared as wisps

I was playing the competitive mode, when one of my dps’s model just randomly disappeared, and, instead of the actual model, blue wisp appeared (i have screenshots). Then, other teammate’s models got replaced by those wisps. After not so long, enemies too. Time-to-time, they were getting back to normal AND they disappeared again. I couldn’t properly target my teammates (I was playing mercy, thank god, it would be UNREAL to aim anyone, cause their visual hitboxes didn’t exist at all), but with enemies it was a total disaster. I wasn’t able to see even Winston…
