I dont think you need to restore system databases to make a copy of production. Because Dev and Prod are completely different instances.

Dev and prod need to match with their schema and not system databases.

To avoid any other problems please revert back your dev system databases from backup. Like if you are updating something on Dev box with the criteria of @@servername then it would update your production(only if this job uses an account that exists on prod, but it is a possibility)

Thanks!!
