[GAMEPLAY] Sion Q AOE not shown properly when warded

This particular game was custom made and consisted of 8 bots and 2 players. Whenever I place a ward in a bush that is Q'ing in, it shows the AOE of his Q away from his character, and then when finally uses his Q it moves the AOE box to a different location so that it aligns with his character.

1. Have start using his Q inside an unwarded bush
2. Have an enemy champion place a ward in that bush while is charging his Q
3. Have release his charged Q
4. Watch the AOE box of his Q shift to the side

I have attached links to multiple videos as evidence of the bug
