Invisible Wards

@40-41 minutes why the hell can they not see that ward? This game is 7 years old and there are still little "bugged" nooks that hide wards. It already is hard enough for most people to remember to ward but having the know EXACT pixels to drop a pink ward or scanner to see those things. I know some of the bushes have this problem like the one that is down and left of blue side red buff or the bush that is down and left of red side blue buff does the same thing if it is in the correct spot.
