I'm using this script for a couple of weeks now and it is getting more bot-like & unstable as time goes by.
I'm running it on anti-pattern mode with activity 3 agression 2 @ east with teletab + 3 food & pots.
Basically it is just randomly running around more lately & not targetting crabs, which not only makes it look more non-human like but also causes a large experience loss.
Hopefully you can work with this.
