BUG - Map disabled

I was exploring Dark Forest and came across a bug where the map was disabled. The minimap showed nothing but a dull outline of circles (like a radar) and the expanded map showed nothing at all (see screenshots). This seemed to affect multiple areas (The Dark Forest, The Western Forest, Forest Encampment) and was not resolved by logging out and in.

It is however, temporarily fixed by restarting the entire client.
