When viewing some replays in a round I was shooting on the August monthly quickplay sweeps, I noticed that the avatar would immediately disappear after taking your replay shot. However, when viewing it a second time via the "watch again" button, the avatar does not disappear.
It doesn't make anything malfunction that I'm aware of, but I thought it was an anomaly worth noting and passing on to WGT ...
I'll send an in game bug report next round ...
