the behav in this visual range 120 building loops dropped stuff in an initial smaller range and sets findings into the signal
human shuttle picks up signal and collects stuff
if the 3x2 doesn't find anything in the set range it increases the range in steps of 2
problem is: it increases range until it finds something and when the goodies are looted the 'compare register' will always exit to the 'is different' even when the 'loot' variable is empty
