I've played Sims 2 for a bit and I've modded in some things but I've been having trouble with meshes for the past two days. I'm getting to my wits end and it's frustrating. I've added some extra stuff to make some Sims in my desired style and yet, they don't want to show up.

I really need some help with this.

I'm using some of Atreya's ear and tail meshes along with a snout one I found. They're not showing up. Please help.
