So, I recently bought a pair of Piranhas to supplement my Tau Empires force. I primed the pieces earlier today and set about constructing them.

After assembling 95% of the first Piranha, I realize that A) it's missing a piece (not still on the sprues, I checked) - the little targetting array looking thing that attaches to the front curve of the Piranha, and B) that there's a couple transparent plastic pieces that I have no clue what to do with.

My first thought was to see if the transparent pieces were the missing front bumper piece, but they aren't. Does anyone else have a clue to either of these mysteries?
