There you have it...all is explained in the above post thnx Cob92
But if there is a notion of a bug in the education system, like if you have 4 cities and all four have universities, so the agents go everywhere in between those 4 cities and not their parent one, who knows maybe it will be corrected in the upcoming patches.
Ther is a bug in the education, @ Rufus ..that happens because the inital wave of students isnt enough to supply the educated workforce in the tech lvl of the college, but you plop down a university and then it works somehow.
I have an even funnier problem...150k+ population city...4000 desks open for education...students migrate to other towns
