Navigation icon is broken

[(PSN)RonGorzon]

In playing the mission "Find the Sentient Fragment: Cressida, Uranus," I found the navigation icon onscreen completely unreliable. It was pointing me in the opposite direction of the ultimate goal. This is a frequent problem in Warframe, though it's apparently much more frequent in Archwing missions. I suspect it's likely a core problem with the engine, and that fixing navigation would require major rewrites to core components. If this is indeed the case, removing the navigation icon from the screen would be more helpful in a mission like this. Alternatively, if there are directional tolerances in specifying the goal, these may need to be adjusted.
