Game Data Incomplete
I am having the same problem for at least 2 weeks now, and I am so tired of trying by myself so I googled it and found this solution and I was so glad but then I looked at the date and it was 2015 and it is 2018, but I tried it anyways, and since origin has had so many updates in the last 3 years one of the steps could not be proceeded, and that was to repair the expansion pack, the way that you put it, I tried and it wasn’t working, so if you know could you please help me . @crinrict
Have you tried a Sims 4 factory reset, and new game without any mods for testing purposes?
Resetting the game to factory settings without reinstalling
https://answers.ea.com/t5/Technical-Issues-PC/READ-FIRST-Troubleshooting-your-Game/m-p/3621199#ResettingAny time Sims 4 starts acting up, that's my go to thing to do. If after the factory reset, the game works correctly, I start putting back my saved games, option.ini file and mods, tray folder, etc.
If the above doesn't work. I'm kind of wondering if something may have messed up during the reinstall when you canceled the reinstall the other day. Have you run Ccleaner to clean the registry?
Ccleaner and it's registry cleaner cleans out temporary files, old registry files, internet cache files and other files that are left behind that are no longer needed. This does not hurt your computer or it's files.
