So I was playing 
i was top
decided to dive me with 
they both ult me at the same time I was the closest possible from my tower but the tower wouldn't hit them nope... it didn't aggro instead it continue to hit minions like I wasn't even there...** and no they didn't have ohmwrecker**.
2: tower shooting summoner spells (visual)
I had this happen to me a couple times last night... not sure what causes it, as it seemed random when it happened.
I've had this happen as well on a couple of occasions. Got attacked under the tower by a Jarvan, Nami bubbled hoping the tower would do it's work, but instead it kept attacking minions (I died of course). Even the Jarvan was like "WTF?".
I haven't figured out what the pattern is yet, but it is annoying when it does happen.
stuff like this should be bumped riot has to know this game broking bug
