[GAMEPLAY] Being able to see Teemo mushrooms in ARAM without having oracle's extract

Hello, I don't see bugs too often, but I recently played a Rumble game in ARAM where I was able to see the enemy Teemo's mushrooms and destroy them even after the effect of oracle's extract seemed to have expired. This bug persisted through death and the whole game in fact. My team mates could not see the shrooms though (I don't think anyone has bought oracle anyways). This meant I didn't need to spend any gold to destroy these traps. The visuals of oracle were not visible and the warning of invisible units in a brush did not work. I think could still see the enemy Wukong while he uses his w's invisibility. Hope you are able to spot this bug soon enough.
