Can't be fixed by reinstalling since it wasn't included in the bsa in the first place, it's suppose to be a skeleton mesh. You could either modify the spell so that it doesn't add the mesh or find another as replacement. If replacing it should be named MidasSkeleSuit.nif and goes in Data\Meshes\Armor\MidasArmor.
Ahhh, well thanks for the information. I copied a file from Curse of Hircine Resurrected named skeleton.nif that I assume is the one that leaves devoured bodies as skeletons and renamed it to MidasSkeleSuit.nif . It got rid of the missing mesh but I'm not seeing the skeleton. As long as I dont have the big yellow mesh replacer I'm happy though. Thanks!
