Every time a create a D or O playbook, it will work for a few games, then like you, my playbook is empty, but my defenders will run up to the line of scrimmage, but will stay in a huddle formation and will be facing the side line.
Once this happens I know my playbook is broke, casue if I go the edit the play book my system will always crash.
It got so bad that my PS4 would start to encounter all kinds of crashes due the to cpb. I had to delete all my games and rebuild my library, but when I did that I could not save any of my game progress, I ended up having to reinstall the PS4 software and start from scratch. I tried to create a cpb again but crashed again.
on a side note, for CPB, whey they don't also have an empty playbook for those of us who want to totally create a custom playbook. They make it so difficult, cause you can't really delete all the play's as some are situational and it just takes too much time to find them and delete them.
