What changed?!

I have been a long time fan of ordering the acrylic pins from here to help promote our shows - our show posters have always made great little pins. I did everything the same way I always do but this time they came out teeny tiny - I guess the default setting changed or something so I've had to re-order and force it to the largest size. I'm hoping the next batch I get will be the size I'm expecting - nice quality of the print and pin but disappointed at the seemingly random size difference.
