Luckily the seam is hidden, so you can't tell, if it was noticeable at all I would return it, and even contemplated it, but having to wait for another, if they even had any more would have annoyed me, and it really was an easy fix.
I know what you mean, my AT-RT (ES of 250 for those playing the CBG game) came with a cracked handlebar and they had no replacements. I basically got a 12" Retro figure for free to make up for it.
