Hi, patch 15.10 is the best for this game yet. Much improved finacial system through several seasons. Even had a player holdout. The problem is my playbook I have used for years has loss the info for about half of the playbooks in it. I keep all my data backed up on 2 different hardrive backups because I am anal. They worked on 15.09. Now that being said, to me it is still worth it using the new patch for overall game. I can build more playbooks.
