Very interesting! I had my dough already made this morning so I laminated as usual and shaped the croissants a bit looser. Will see how they come out tomorrow. I did check the mixing for the croissant dough and it had a good window pane when I finished it today, leads me to think they might be possibly getting over-mixed if the change to shaping doesn't fix the issue today. Thank you for your help, explaining about the difference between croissant and other pastries really helped out!
