Illaoi Tentacles

Excuse me Riot? Why isn't the indicator for Illaoi's tentacles showing up when they smash on the ground (this is for her E, when you leave the zone and you become a vessel or something)? Like, I understand they maybe can't be targeted when she ults, but that's no excuse for why the indicator is invisible. I don't want to be walking and then, oh f*ck I'm dead because I had no warning this tentacle that spawned had no indication, OR an animation!!!! I just died!! So can you please fix this???

(It's either this or I'm totally oblivious to something I never knew about. Please let me know if this is supposed to happen, but I think it isn't)
