Bad gmod build?

Ok I was in the middle of scripting my gamemode and I realized that when I was in game my health bar was purple and black checkerboards. It’s not even using a texture. For some reason stun sticks are errors.

I have

hl2 deathmatch
hl2 episode 1 and 2
l4d2 and some other games that are not valve.

So please do not say that I do not have the games… I also realized when I spawn a zombine I got this message in my console
MDLCache: Zombie\Zombie_Soldier_animations.mdl needs to be recompiled


I never encountered these before , they only recently started. Did Garry have a fail build on gmod?
