[BUG THREAD] The Sims 4 CAS Demo

A bug I'm having is that I'm unable to remove one of my sims from the gallery. When I click the green cloud in the gallery it shows the sim being removed, but when I go back to my page the sim is still there. I've closed the CAS demo and started it again, and it still won't work. It's stuck in the gallery. I've removed a few sims before without any problems, but for some reason this sim isn't able to be deleted from the gallery.
