Earlier todat Space-X Launched some more satellites, on the video @ 23:46 it looks like something is moving around like "The Mouse" You will see it on top of the ring above the thrust burner there. Someone said it might be a piece of Foil that ripped off. I agree that it doesn't move like a mouse. Someone else said it was a piece of Frozen Fuel, possibly. I think if it was anything on there moving at the speed it was supposedly it would move differently.
a still of said unknown oblect.
