@NameesaiLayy , personally, I do not use Mods for Sims Medieval. However, Sims Medieval shares a similar architecture to Sims 3. What this means is, what works for Sims 3 should work for Sims Medieval. There is a special set of files you need to add to the Sims Medieval folder before you can add mods or CC. (Again similar to Sims 3). I got my folders from Mod the Sims and you should be able to search their Sims 3 section for the information you need to copy and add these special folders. Just follow the instructions on that forum.
