I received the Thunderworm from Reaper and it is marvelous. I have six pieces for it. The wheels are the same, obviously. But it seems that I have an extra piece. I have two axle-beam supports. In all the images where this product is assembled, it doesn't seem to have a second one. Should I have only rec'd five pieces or is there a place where the second axle-beam support is supposed to go that I missed? Thanks! EDIT: I sent an email to Reaper support and they indeed have confirmed that it is an extra piece. This product only should have five parts. Question answered!
