I have downloaded a sim off the internet for my Sims 4, I have made sure that Custom Content is allowed but I still can't find my Sim in My Library! I have taken all files, four of them that are tagged orange in the picture! However I have checked My Library multiple times after restarting my Sims 4, but I still haven't been able to find my Sim! Help PLEASE!
