Neeko not taking damage from Elise Q in spider form (and other abilities?)

In an ARAM game I just placed, Neeko was consistently taking no damage from my Q. An Ezreal on my team also complained about her not taking damage. I don't know if/how many other champions this applies to. I'm positive it wasn't the clone. Also she was very low on health both times; I don't know if that's relevant. Please look into this bug and fix it.
