On the custom playbooks pages, when creating an offensive playbook, it says right under the Create New Playbook button, "To be valid, an offensive custom playbook must contain at least 3 run and 3 pass plays."

I created a playbook of 8 plays, 4 runs and 4 passes, to test these plays. It says the playbook is invalid. Either the information given is wrong, or there is a bug. I'm assuming it should be 10 run and 10 pass plays, which it was in PF19... Should be a quick fix

Thx, will take a look. The min/max is configurable so the text probably needs to change based on settings.
