How long this bug on Illaoi will last?

Her Vessel/Spirit + Slam attack effect is bugged for a long time already and it's still not fixed. For me as Illaoi player it's frustrating and even makes me sometimes dead, because this effect is bugged.

_"Each Tentacle will autonomously attack the closest Vessel / Spirit once every 10 seconds." _ It means that every "new" tentacle (every tentacle, not just spawned) that is in range of Spirit/Vessel will attack this without command. Sometimes it does, but sometimes it doesn't. It sucks when u make an enemy a Vessel, u have Tentacles around you and u can feel safe cuz if he wanted to attack you, all tentacles will attack him. But they dont, really often! Riot please fix it. Same with the Spirit. Sometimes when you pull out someone's spirit, tentacles just stays.
