Icons & Heroes - Offline Not Updating Legends Roster
The introduction of Icons & Heroes in career mode brought me back into the series after a hiatus. Ultimate team makes it almost impossible to not spend more hard earned money and plenty of it to play...
Solution given by EA - an online career save file needs to be made that uses the icons you select to include. And from there that same save file can be accessed offline. However, if you start an offline career mode, only the base 4 icons will be available. So before servers shut down for good on this game, if you are interested in using icons you unlocked for career mode (or other single player modes), make your saves of who you want to use ahead of time for the offline future.
