Fixed, A while after posting. If an admin sees, please delete.
Remove your Lua code completely from the server.
Go into the cstrike folder and copy the “css” folder into orangebox folder and start the server. If that doesn’t work, remove the css folder from orangebox folder and copy over the whole cstrike folder. I can’t remember which one that works.
Anyways, remove the lua code completely because players already have all the default models if they have the correct game such as CSS or TF2.
