First I need to hit planck for telling you to use east.
Ok that done, you need to set it to west. Also, as I asked to be put into the readme (good job whoever wrote it!), the bugs will only attack something that is close enough to it, about 200m or so, maybe less. And also, if you are more than about 50m away, it won't attack you unless it knows about you (firing your weapon will give you away). Yea the script does suck, buy like I said at the time thats the best I could do.
