Stress marks on Optimus Prime Trailer?

Hi,
I have a question for you guys. I just bought a Hasbro Reissue Optimus Prime off of ebay. However, when I got the figure I noticed that there seem to be a large number of stress (or possibly mold?) lines in the trailer. Just wondering if this was a common thing with these commemorative reissues. The Prime I got was an open box and was listed as in excellent condition. So of course I'm a bit disappointed. Just wondering if this was a quality control issue or if it's possible it got damaged by the original owner or during shipping (it was kind of poorly packed too)?
Thanks!
