Thanks for all the info but I think I might have figured it out, I had the maximum of 144 groups for opfor or close to it and apparently this is too much for Arma to handle at once (or my PC, tho i dont think so) So I used a Caching script(murk spawn)and it seems to work in editor preview , the patrols now fire whenever they see me but for some reason its not working in multiplayer.
