"Mission Select" options disappeared
Earlier today I finished the GDI campaign and was browsing through the menus, on the "Mission Select" screen I saw that I was able to replay all my previous missions as well as the alternative A/B/C missions. That's pretty rad.
I closed the game and reopened it a couple hours later and now there's nothing in "Mission Select" besides the first mission, all my saves are intact however.
Any help is appreciated, I wanted to go for 100% and don't feel like spending another five hours to complete missions I've already done ☹️
edit: My bonus unlocks are gone too :'(
edit2; And my options appear to be reset
This might be due to keeping too many savegames; a side effect of the handy quick save feature and the fact savegames can't be selected for overwrite, combined with a full screenshot being saved per savegame as "thumbnail".
Try deleting a bunch of your savegames and see if that remedies the issue.
