first of all there is no door it is on a island...
here is a pic of it
I am saying I could make the rock disapear after they are done with it...
then every once and a while I could make them like walk around so they would have to walk back to there rock to get finished with it...
that would be annoing but like it would stop macros if I have the walk around thing like randomly 5 times per rock... or something
