ive noticed since dark avatar that all survey ships when set to auto survey go directly to an anomalie evan if the they should not be aware of the anomalie (eg an anomalie in unexplored space)
That has always been the case, even in the base game. Surveyors have special anomaly-detection equipment
since toa ive noticed that enemy constructors will do the same
and head straight for the nearest resource node i spend turns and turns
looking for them only to have a civ halfway across the universe pop up
a starbase within 2 sectors of my homeworld
How do you know they have not scouted them?
