After getting beavered 3 times in a row I finally get into a match, only I don't see anyone, but I can still see the kill feed going. I thought I was going to get beavered again, but a moment later everything loaded in fine.
I thought everything was OK until I noticed nobody could see me, and I couldn't deal any damage with anything other than explosives/aoes.
After somehow managing to kill myself with Mountaintop my game went back to normal and I could be seen again.
How does this kind of thing happen?
