I can't be arsed to go through that mission again. Anyone want to describe or post a video showing this surprising and out-of-place thing?
You shouldn't have to go through the entire mission - your Shepard's Restart Mission checkpoint should be right at that part.
Ah. So it is. Not seeing anything that jumps out at me without a liberal dose of imagination, though.
Using a liberal dose of imagination, all I see is a cloud that looks like the Bat-signal. Which is crazy because Batman isn't based out of London.
