I doubt they were on sale because of a known problem with a batch. Golden would have wanted them back … not sold. What you are probably seeing though is their Aquazol binder.
If the store will not help you I would contact Golden directly. I would think they would send you some replacements if you showed them some photos and explained what you experienced.
