Duviri quest lock-on impossible

Hi Tenno, thanks for the report. You should be able to lock on but you must first have to be looking directly at the enemy Dax for the UI to pop up. It is hidden while you are not looking at the enemy so as not to take up too much of the screen when a player does not want to lock on. 

Having said all that, we'll take note of the feedback that this isn't clear!
