Can you change the default Lat/Long values to be 0 instead of 999 so that at least the map would work without having those parameters set? (Lat/Long of 999 doesn't exist and seems to break the component!)
We also found this out, but the breaking of the map only occurs from Experimental version 3.32.4, which was released this Sunday (4 March 2018). Before that, the map just chose some center by itself. So yes, this should definitely be fixed, but it's a very recent problem (we had to make a quick fix in production for it).
