Re: Can't play dlc offline

@skippyjon  What happens if you temporarily use your phone as a mobile hotspot, then login to Origin in online mode?  Sometimes it only takes one online login to "remind" Origin that you own everything.

Before you try this though, please copy the pack folders to a second location on your hard drive.  They're inside the folder that contains the Sims 4 program files (the folder in Program Files (x86)\Origin Games), and each pack you own has its own folder, labeled by type of pack and release order.  For example, the folder for Seasons is EP05 because Seasons is expansion pack 5.  You can ignore the pack subfolders inside the Delta folder; that's not the same data.

It's possible Origin will delete all these pack files and try to make you redownload them.  (Hopefully not, I'm just saying it does happen.)  But you can pause the download and copy back the folders.  When you resume the download, Origin should verify the presence of those folders instead of redownloading them.  It might repair, but that should be it.

Once you launch the game while online, you should be able to go back to playing while offline.
