Finished story mode but last characters are locked
We have two save games, one for our son, and one for me and my wife. We finished Story mode and all characters were then unlocked to buy but our son finished Story mode and the last 7 characters are still locked, so we can't unlock the bounty hunters.
Is there something else we have to do to unlock the last 7 please? We have seen the character unlock codes buy there aren't codes for all of the remaining characters.
We tried Activision tech support and they say it is a gameplay issue, not a bug. Thanks.
