Your method helped a lot) but if you forget to remove these objects just from one lot - they will load and go back to the save again multiplying in geometric progression, so it's a lot of work to clean up the save properly. Still the old good advice to avoid entering the build and even CAS mode during festivals can reduce the amount of these "high-flyers".
Ah good to know! Thanks! I didn't know that using CAS or BB during festivals would cause this too...
I noticed that those objects would start moving up like in the video, when I cleared out my personal save file and reproduced & recorded that error in this brand new save game within a new Sims 4 folder, without mods of course. I can reproduce it that way every single time. And I only traveled with that sim, didn't go into CAS or BB. The objects moving up weren't even festival specific. Those are the standard street ones which would be cleared up when a festival starts. I don't know if this helps any further. But I hope 🙂
