When your champ walks halfway of the range indicator to the target to fire at max range

How do i turn off this annoying bug that makes me walk to the champion to launch an attack that is CLEARLY within range of the spell range indicator. I can on;y hope this isn't happening to anyone else with no ping changes. I CLEARLY remember RIOT discussing pathing changes and range changes that help fix said pathing issue but alas, no fixes are present. Is there a mod i can use to fix this bug?
