ok im pretty new to garrys mod but i was messing around with the command prompt and i put in ai_disabled 1 and now none of my NPCs work no matter wut i try

HELP PLEASE

ai_disabled 0

i tried that but it isnt working

You see the little button with “Ignore Players”, is that ticked?
Untick it.
What about the “AI disabled” box?

Both are under the NPC tab.
