Hello people of the night

So ~sometimes~ on the map I see the Fever mark. The thing that irritates me is that no-body is there. Now you could say "Ninja" and be done with it but other people have also seen the mark and I saw people spamming AoE's but no one appeared. I have seen that mark on the same spot in 3 different games already but no person to it?!?!

Am I being outplayed by a superior Ninja that mocks me?

Here a video of the spot.
