Heim turret bug

Heim's turret shots are bugged. The shots are travelling insane distances and it appears to be aquiring the targets at equally large ranges.

by large range i mean the distance between the two first mid towers or more, and sometimes the shots will follow you to base from lane. It appears as though they only do the base damage, without any scaling, and sometimes no damage at all, but still, something is wrong with them. I can't reliably reproduce it. It appears to happen randomly, but, it does happen every game i play heim or play against him. I don't know what triggers it, but it happens often enough that it shouldnt be too hard to see.
