minor visual bug with nid

i laned against quinn and singed at some point during the laning phase the arrow link that shows me who has stepped on a trap or hit by a spear was on them all the time. sometimes i would be nowhere near them and if someone else had vision of them it would draw all the way to them. It was in a game of arurf so that probably had something to do with it. I have the replay saved on lolreplay but I doubt it would help find what caused it.
