I have an odd glitch too with The Sims. :(
I recently re-installed the Sims and started playing - everything good so far! (Running game as administrator and without the Windows Update KB3086255).
Then after re-zoning a lot and building and completing a community lot, when I went back to play the families in the neighbourhood, there was a prompt "Missing objects - some objects could not be loaded"???
I had played two families the day before.
There is no CC installed and the games was patched with the Double Deluxe patch and the patch when installing Making Magic.
I have identified that some wall lights are missing as I use these a lot - a white diamond light and the blue one, I usually use in the bathroom.
Where could they have gone?
Has anyone else had this problem?
Will I need to re-install?
Thank you in advance for any help you can offer. :)
