Gameplay Darius Bug

Issue: When playing as Darius there are times when instead of attacking a target I will simply walk up to it. I have witnessed this bug against minions, towers, and champions and makes the game unplayable for me. Will not be able to play the game until this problem is fixed as having auto attack RNG is too difficult to overcome. (Have not tested this bug on other champs). Appears to happen more frequently after Darius' Apprehend.
