I'm having the same issue as a couple of others, but the "fixes" haven't helped me. I had to reset my pc due to a windows error which deleted my sims 4 game. I went to install the game again and it was running fine, the problem is I have all of the expansion packs, all but one game pack, and all but three stuff packs - this would take a long time to reinstall everything and I cannot leave my laptop running for days. I let the base game install before closing out, figuring I could download the rest later, but unfortunately that doesn't seem to be the case as instead of a "download" button in the more section when trying to reinstall my games there is a details button.
I am 100% certain that the content is missing, when I go in game the icons are colored instead of grayed and a notification pops up saying that the games are downloading in the background (but they are not). I have tried repairing the game, updating the game, logging out only to log back in, but none of this has worked. Uninstalling the game and then reinstalling it allows the packs to be queued and they will start downloading, but that will take too long and, again, I cannot leave my laptop running that long. Any ideas? If not, do you know how we could alert origin/the sims team to this issue to get it fixed?
