PK3 character won't load MAINCFG. (21.21 bug?)

[Globx]

I took the opportunity to make my character .wad into the recently added .PK3 format, when I start the game, his character select portrait is not present but he can be accessed only via through the devmode and "skin" command. Is this a bug or is character select setup differently in PK3s than in wads, should I just revert to wad for the time being?

Layout:
(misc. graphics folder)
(sounds folder)
MAINCFG
S_SKIN
(sprites)

MAINCFG is a SOC lump, so you need to put it in the "SOC/" folder.

Thanks! It works now!
