Installed expansion is not showing up in-game
I just bought the Supernatural expansion through Origin. When I installed it, the external installer warned that the previous installation was newer than expected, and that Supernatural might not be compatible. When it was finished, the option to play the expansion hadn't yet shown up in the Origin client, only to install again. So I quit and restarted Origin; now the option to play the expansion was there, but when I launched the game, it launched as the Late Night expansion only — the Supernatural content was nowhere to be found in-game. What happened?
It seem to me like there was a problem with Origin, that's why you ended up with a game not properly installed. In the future, before installing a new expansion pack, you should check for anything that might conflict with origin. https://help.ea.com/article/programs-that-may-cause-conflicts-with-origin
