[Gameplay] Killing Illaoi's tentacles counts as a ward kill for your post game statistics

In this game I went up against an Illaoi and was very diligent about destroying her tentacles. I only killed maybe one ward the whole game but in the post game statistics it said I had killed 46 wards! The only explanation for this is that the game is counting Illaoi's tentacles as wards when you destroy them. I track all my statistics in an excel spreadsheet so this definitely makes that more difficult.
