So the cursor for the script will just hover over the rock crabs that aren't aggro yet and won't walk up to them to attack, and instead will attack other peoples crabs when theirs pops up.
Edit: Worked perfectly fine the first time I used it, not sure if I switched any settings or anything but I dont think that should have made a difference. Don't like the idea of attacking other peoples crabs cause some people get angry and then attempt to start a convo which may lead to reports lol.
