Well, the title obviously says it all. I'm having issues with .packages that have custom meshes. I'm not sure if furniture is doing this too(I don't have any custom furniture), but it's happening with outfits and hair. For the outfits, it just shows an invisible space between the feet and head. For hair, it shows part of the texture, but the mesh doesn't show at all. It just looks like a texture was glued to the sim's head.
I'm running the game on a Mac Leopard and I have sims patched up to 1.3.
I've tried deleting caches, removing my mods folder and putting it back in, deleting my neighborhood and starting a new one, but the meshes just won't show up.
Those are both custom hairs.
