Missing waking dead gun textures and sounds

[Fugikuro]

I have been trying to play waking dead but it seems that just about every gun except for the basic weapons (smg, 357, sniper, ect.) are purple and black checkerboard pattern and don't have any sound effects when fired. I can still play through the level and all the guns and animations for them work fine. I would still like to know how to fix it so i can play through and in case it happens on any other maps.

you need to have CSS mounted since they are CSS weapons.

Ah. That makes sense. Doesn't explain why the animations still work though.
