Elixir of Iron in Co-op vs AI

I discovered that after using an Elixir of Iron in a Co-op vs AI match, the visual range of turrets increases (The targeting circle that appears when near turrets) however they don't target u unless u are in the normal range. I have only tested this with the Fountain Turret. I have not tested on normal turrets but I will edit this if it effects them as well and will try to get some screenshots. (Also I was playing Cho, with max stacks during the match I discovered this bug). After testing this it appears this only occurs when I play cho'gath and to inhib and fountain turrets
