T-Posed NPCs

When the gamemode im working on (http://www.facepunch.com/threads/1105510-Excl-s-nazi-zombies) spawns Zombine NPCs (the ones with the grenade) they spawn in a T-Pose, I don’t know what causes it. How can I fix this?

Still need help on this

Why did you put a Wii icon on this?
And is it the normal zombines, or edited ones?

Its the default HL2 zombine. A combine zombie.
