I'm having the same issue, and expect anyone who isn't a sub and doesn't have artifact auth has it too. These crystals were never artifact equipment before, even if they did have a purple border. If they were, I wouldn't have spent my cc to unlock them in collections and wouldn't feel like I'd been cheated now. Now, the only toons I have that can use them are the ones with artifact auth. Since I unlocked these a *long* time ago, every single one of my toons (at least 8 per server) with the exception of the 3 (total) that have artifact auth are pretty much borked.
I'm not sure what "investigating" needs to be done. These crystals did not require artifact auth before the patch and now they do. That goes for all of the +41 stat level 10 crystals.
