I have completed campaign mode and received the awards for doing such. Now that I am going back to replay missions for collectables, I can only replay the first 3? Any clue why?

Have a look at this thread, and specifically this answer. Waiting for a "real" fix, but there is a workaround that seems to work.

Missing completed campaign missions

Having a similar issue, however mine don’t save at all! Very frustrating. I can play through missions, then exit the game to windows, then when going back into the game it’s missing/doesn’t exist... only have the option to start the campaign as though I never played/started it...

Same here, for xbox. did you play the first 3 levels on the ea access trial? It seems like only people who played it during the trial have this problem. I read the workaround, but i have around half the arcade finished and don't feel like losing that. Hope this gets fixed soon.

Yes. I preordered, but played the 10 hour trial from ea access... Thank you. Helps to know I'm not the only one.

I preordered and preloaded. But never played the trail. Will have to give a shot still to see if it works.

@ShadowTakker Did the workaround fix your save issue? I'm having the exact same problem as you. I've restarted the campaign 3 times now.

I have the same problem, but I didn't have EA access.. I had the deluxe edition.

Hi @s4mw4r. Still no changes for me. Needs to be a patch released.
