Nidalee Passive - Hunted arrow indicator doesn't go away

During an ARAM game as Nidalee I noticed that my Passive indicator proc'd on the enemy Illaoi and never went away.

From what I could tell, it didn't give the ability bonuses (such as the range indicator to actually utilize empowered W) unless she was actively marked with Hunted (though, admittedly, I didn't properly test this). This persisted for the whole game and regardless of range. It only dropped if she died or if someone else was marked and was in range of the Hunted indicator. If she died the arrows would reappear once she came back into my vision. The indicator would continue to work even when I was dead.

I don't remember what caused this to happen, but it was early on in the game. I killed her a little while after this happened as well but the indicator didn't go away.

Below are some images I took of the incident. The first one shows the indicator to Illaoi even when she wasn't marked as Hunted, and the second one shows that the indicator was still there after I respawned. I also had an image of when I was dead but I stupidly saved over it.
