RED ALERT UPRISING NOT FOUND ON MY LIBRARY WHILE I HAD IT SINCE LONG TIME AGO

Funny (?), what if You don't own Red Alert because Uprising was a standalone extension?

Update: Just half an hour after writing here (inkluding a windows reboot), the game is now showing up in my library again - but now Battlefield 4 is missing.

I think this is related to some serious EA App bugs and I can just recommend to everybody to backup all You have/can as long as the games're still accessible.
