@Blackredminty Sorry, I didn't think that was your video since you said you were playing in France and the video is set in China. It's still hard to watch though, especially with the voiceover; a shorter video with no commentary or (even better) a simple description of the problem is much easier to process.
Please try adding NRaas ErrorTrap, Overwatch, and Traveler to the mix, and let me know whether it helps. Delete the five cache files in your user folder as well:
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
Your dxdiag lists a bunch of network errors and a couple from Sims 4, but none from Sims 3. So if the above doesn't help, please look for related errors in the Reliability Monitor. Hit Windows key-R and enter "perfmon /rel" without quotes. You'll see a list of errors and updates, with a column for each day. (Today is all the way on the right.)
For any errors that mention Origin or Sims 3 from after you add the other mods, click "View technical details," then copy the information and paste it into a reply here. Sometimes the Reliability Monitor doesn't update right away, so if you don't see any related errors, be sure to check back an hour or two. The timestamp on the initial chart can also be off by up to an hour, so that's not an entirely reliable metric, but the one within the technical details should be accurate.
