Custom Heads Missing in Alpha 8

[jabbamonkey]

In Alpha 7, I created custom characters skins for the game. There were some minor issues with the textures, but I thought they looked good. However, since Alpha 8, the heads are now missing from the humanoid characters.  Did the naming convention change?

For example, I have the 3 AVERAGE head components placed in the following directory:

mods/core/texture/things/pawn/humanoid/heads/male/Male_Average_Normal_back.png
mods/core/texture/things/pawn/humanoid/heads/male/Male_Average_Normal_front.png
mods/core/texture/things/pawn/humanoid/heads/male/Male_Average_Normal_side.png

While I have graphics for all the head types, none of the heads are appearing in the game (average_normal, avereage_pointy, average_wide, narrow_normal, narrow_pointy, narrow_wide)

Any ideas?
