Pretty sure Driftor had a video about this glitch and stated he hoped it would be fixed. The was some time ago, obviously nothing has been done.
The target finder was just a bad idea overall. I dont use it at all and think it cheap. Another thing that is super cheap but I utilize ALL THE TIME is league Search and Destroy is the MMS. Another thing that shouldnt be in the game but is much more helpful than the TF IMO.
That being said though neither is a good idea IMO.
