[Gameplay] Ranged vs Ancient Golem (Bluebuff)

when playing adc i often will take the purple side blue buff. lately there has been a bug/glitch where with Jinx or Sivir i can take the golems without them even attacking me. they will move forward then stop before they move pst where the little monsters are allowing me to free farm them without any worries of taking damage. Sivir doesn't have the longest range so i believe there is some sort of bug going on because the golems wont leave their camps when playing ranged but will hunt you down when melee

i have had this occurs about 5 times so far
