Zombies no collided?

Hi there, I was wondering if someone knew a fix for this, I’m aware that I’ve posted about this in the past, but I need to know again what the answer is;

Zombies aren’t touching people. They are doing no damage whatsoever when they get close enough, and instead are just sinking into the players. How can I fix this, via a code method on spawn would be best. :slight_smile:
