Commandos and Shotgunners get stuck on ledges

Valherran:

Levels 1-10 is where it happened the most, if they try that slide goin off a 
ledge, they definantly get stuck, mostly this happens witht he SHotgun Zombies. 
The Zombie Commandos for me were just strange, they like to slide alot and not 
fire at me. But I despise that damn slide because of that screwy hitbox it 
causes. Meaning alot of times you hit them dead on and they take 0 damage, 
hence is why it is unfair in realism.

Also Commandos are often seen by my running around without shooting. They don`t 
attack me at all
