Fixing the ECPD Phase 2 Officers (Metrocop AI Edition)

[The Fennec]

Hi there, I've made an attempt to make the ECPD Phase 2 Officers with npc_metropolice AI since people have been asking for it. It works perfectly fine, although I want to add more into the script by changing the metrocop's health so that it can go toe to toe against overpowered weapons and snpcs that are used within the server I go in. The NPC pack uses an unconventional script to change it's model since the script located in the gmod lua folder cannot change the metropolice's model. Every time I try to change it's health value, the script breaks. I have little to no experience with lua since I mainly make 3d models, so any help would be much appreciated.

Here's the code:
