Ok, this bug may not be "game changing" but it is most definitely a bug.
Steps to achieve the bug:
*1- Right click on an ant hill and click "Raid"
*2- Now if done correctly, the ants will aggro you of course; So run away
*3- Keep running until the ants stop aggro
*4- Now return to the Ant hill the same way as you ran from it
(On your trip, you will notice that the ants are now walking in circles about 2 mini maps from the Ant hill, also there will be non guarding the ant hill, making it very easy to raid the Ant hill without losing 1 shp or hhp)
Tested about 5 times, and always had the same outcome. (Adding some kind of Move Towards anthill x and y once losing aggro would seem to be an easy fix.)
Back to testing,
