When casting the eye in the scrying region east of the world boss Deepreave Quag in Apogrypha it sometimes seems to have been cast from the sound it emits but it is invisible.

I don't know if it is a bug or it simply spawns inside the rather uneven terrain. It works better when going up a hill and cast it there. This makes scrying extremely difficult and annoying. Specifically due to the imposed cooldown on the eye.

Also on one occasion the site with the item inside was just a pile of dirt and not highlighted as usual.

I really urge the devs to change this.

Ideally the casted direction indicator spawns directly at player position, let's say waist height in order to avoid it being cast inside the terrain (unless it is just a bug but I guess it is more a terrain issue).
