Since the last update of Pokemon Go (6 December, Android 0.49.1) my game vibrates too often. It is exactly like the 'new-Pokemon-on-the-map', but there are actually no new Pokemon. Is this intended with the new update
It is not because I got another notification, because they all get sent to my wristband, my phone only vibrates on in-game vibrations.

This bug has been fixed as of the latest update, 0.51.0 Android/1.21.0 iOS
According to this thread it is most likely a bug that causes vibrating whenever Nearby (not Sightings) list updates.
Update: Niantic confirmed that it is a bug.
