Certain Items become errors or don't exactly install?

I have certain addons, like source recorder, tactical weapons all-in-one pack, and more. But they don’t appear on my spawn list or menu.

Tactical weapons work, but models show up as errors.

Is it because they’re outdated?

You need CSS for the Tactical Weapons pack.

Can you explain the source recorder then?

Pretty sure the Source Recorder is outdated.

Extremely outdated. Using console commands and binds are nearly as simple.
