A serious turret targeting system bug is ruining gameplay with Heimerdinger.

Heimerdinger is horribly inconsistent right now. I posted a few weeks ago about how it felt like it was harder to last hit as Heim and how his turrets would randomly switch targets even without the enemy being out of range and without Heim marking something with an AA. I tried to pick him up again and it's just so obvious that his turrets are completely screwed up right now. My CS has gone from about 90% or higher with Heimer to 70% or lower. I've never been outfarmed as Heimerdinger except by Yasuo or Ziggs maybe, now anyone gets close or higher than me.

The bug is easily repeatable. I'm not sure exactly when it happens, but in every game it happens to me. His turrets will randomly stop targeting an enemy champion within range, they will get a minion to 1 turret hit from death and then switch targets. They will sometimes even ignore the target Heim has marked, although that is less often than them just switching targets randomly. Keep in mind this is all while the enemies are within range, so I'm certain it's a bug and not just how it's meant to be. I push hard as Heimerdinger in most games, so that may be a factor if not everyone plays quite like me.

Please look into this. There are some games where this doesn't happen often and others where absolutely everything goes wrong that can go wrong with the turret AI.
