As shown below, the flare of Cetus Wisp's dissapearance shows up even when the Wisp is collected.

Here is a Wisp I've located

As seen here, the Wisp is picked up.

But after a while the flare still appeared.

The minimap on the images shows that every one of them is taken on the same place, so it was this very Wisp that caused the flare.
