When I load my custom characters they don't show up on the character select screen?

[MTF]

They load without any errors, and here's the S_SKIN(S) and the SOC_PLAY file

#

the ground to swing
her hammer.

her hammer while in
the air.

In the SOC_PLAY section for Gritstone Knuckles, the Gritstone#Knuckles is in the SkinName line instead of DisplayName, hope that helps!

Edit: The issue is only in the .pk3 file, but the SOC_PLAY in your thread does work!
