Cursor on map vanished

After I got far enough out on my map while looking for a beehive, the cursor on the map literally vanished, I did not see when it happened but when I looked again it was gone. I'm not sure if this is a feature or a bug so I'm going to put it as a bug.
Edit: I should also mention this is happening on more than just this map, it's happening on my other 2 (all of which are different sized maps)
