I have read about the difference in glue formulation with regard to the stickers for the meeples. While I could just as easily use an adhesive of my choosing to affix a fallen sticker, I would rather grab the print that has the new formula already applied. Having said that, how do I distinguish the latest batch from previous ones without popping open the box? Some retailers may have prior stock still sitting on the shelf as I peruse the section. Note: I have not handled the expansion, so the answer may be quite obvious to those who have.
I don't think any retailers actually got stock yet, so I would expect all copies to be "fixed".
